Wasp supports e-mail authentication out of the box, along with email verification and "forgot your password?" flows. It provides you with the server-side implementation and email templates for all of these flows.

## Setting Up Email Authentication

We'll need to take the following steps to set up email authentication:
1. Enable email authentication in the Wasp file
1. Add the `User` entity
1. Add the auth routes and pages
1. Use Auth UI components in our pages
1. Set up the email sender

Structure of the `main.wasp` file we will end up with:

```wasp title="main.wasp"
// Configuring e-mail authentication
app myApp {
  auth: { ... }
}

// Defining User entity
entity User { ... }

// Defining routes and pages
route SignupRoute { ... }
page SignupPage { ... }
// ...
```

### 1. Enable Email Authentication in `main.wasp`

Let's start with adding the following to our `main.wasp` file:

<Tabs groupId="js-ts">
<TabItem value="js" label="JavaScript">

```wasp title="main.wasp"
app myApp {
  wasp: {
    version: "^0.13.0"
  },
  title: "My App",
  auth: {
    // 1. Specify the user entity (we'll define it next)
    userEntity: User,
    methods: {
      // 2. Enable email authentication
      email: {
        // 3. Specify the email from field
        fromField: {
          name: "My App Postman",
          email: "hello@itsme.com"
        },
        // 4. Specify the email verification and password reset options (we'll talk about them later)
        emailVerification: {
          clientRoute: EmailVerificationRoute,
        },
        passwordReset: {
          clientRoute: PasswordResetRoute,
        },
      },
    },
    onAuthFailedRedirectTo: "/login",
    onAuthSucceededRedirectTo: "/"
  },
}
```
</TabItem>
<TabItem value="ts" label="TypeScript">

```wasp title="main.wasp"
app myApp {
  wasp: {
    version: "^0.13.0"
  },
  title: "My App",
  auth: {
    // 1. Specify the user entity (we'll define it next)
    userEntity: User,
    methods: {
      // 2. Enable email authentication
      email: {
        // 3. Specify the email from field
        fromField: {
          name: "My App Postman",
          email: "hello@itsme.com"
        },
        // 4. Specify the email verification and password reset options (we'll talk about them later)
        emailVerification: {
          clientRoute: EmailVerificationRoute,
        },
        passwordReset: {
          clientRoute: PasswordResetRoute,
        },
      },
    },
    onAuthFailedRedirectTo: "/login",
    onAuthSucceededRedirectTo: "/"
  },
}
```
</TabItem>
</Tabs>

Read more about the `email` auth method options [here](#fields-in-the-email-dict).

### 2. Add the User Entity

The `User` entity can be as simple as including only the `id` field:

<Tabs groupId="js-ts">
<TabItem value="js" label="JavaScript">

```wasp title="main.wasp"
// 5. Define the user entity
entity User {=psl
    // highlight-next-line
    id                        Int           @id @default(autoincrement())
    // Add your own fields below
    // ...
psl=}
```
</TabItem>
<TabItem value="ts" label="TypeScript">

```wasp title="main.wasp"
// 5. Define the user entity
entity User {=psl
    // highlight-next-line
    id                        Int           @id @default(autoincrement())
    // Add your own fields below
    // ...
psl=}
```
</TabItem>
</Tabs>

<ReadMoreAboutAuthEntities />


### 3. Add the Routes and Pages

Next, we need to define the routes and pages for the authentication pages.

Add the following to the `main.wasp` file:

<Tabs groupId="js-ts">
<TabItem value="js" label="JavaScript">

```wasp title="main.wasp"
// ...

// 6. Define the routes
route LoginRoute { path: "/login", to: LoginPage }
page LoginPage {
  component: import { Login } from "@src/pages/auth.jsx"
}

route SignupRoute { path: "/signup", to: SignupPage }
page SignupPage {
  component: import { Signup } from "@src/pages/auth.jsx"
}

route RequestPasswordResetRoute { path: "/request-password-reset", to: RequestPasswordResetPage }
page RequestPasswordResetPage {
  component: import { RequestPasswordReset } from "@src/pages/auth.jsx",
}

route PasswordResetRoute { path: "/password-reset", to: PasswordResetPage }
page PasswordResetPage {
  component: import { PasswordReset } from "@src/pages/auth.jsx",
}

route EmailVerificationRoute { path: "/email-verification", to: EmailVerificationPage }
page EmailVerificationPage {
  component: import { EmailVerification } from "@src/pages/auth.jsx",
}
```
</TabItem>
<TabItem value="ts" label="TypeScript">

```wasp title="main.wasp"
// ...

// 6. Define the routes
route LoginRoute { path: "/login", to: LoginPage }
page LoginPage {
  component: import { Login } from "@src/pages/auth.tsx"
}

route SignupRoute { path: "/signup", to: SignupPage }
page SignupPage {
  component: import { Signup } from "@src/pages/auth.tsx"
}

route RequestPasswordResetRoute { path: "/request-password-reset", to: RequestPasswordResetPage }
page RequestPasswordResetPage {
  component: import { RequestPasswordReset } from "@src/pages/auth.tsx",
}

route PasswordResetRoute { path: "/password-reset", to: PasswordResetPage }
page PasswordResetPage {
  component: import { PasswordReset } from "@src/pages/auth.tsx",
}

route EmailVerificationRoute { path: "/email-verification", to: EmailVerificationPage }
page EmailVerificationPage {
  component: import { EmailVerification } from "@src/pages/auth.tsx",
}
```
</TabItem>
</Tabs>

We'll define the React components for these pages in the `src/pages/auth.{jsx,tsx}` file below.

### 4. Create the Client Pages

:::info
We are using [Tailwind CSS](https://tailwindcss.com/) to style the pages. Read more about how to add it [here](../project/css-frameworks).
:::

Let's create a `auth.{jsx,tsx}` file in the `src/pages` folder and add the following to it:

<Tabs groupId="js-ts">
<TabItem value="js" label="JavaScript">

```tsx title="src/pages/auth.jsx"
import {
  LoginForm,
  SignupForm,
  VerifyEmailForm,
  ForgotPasswordForm,
  ResetPasswordForm,
} from 'wasp/client/auth'
import { Link } from 'react-router-dom'

export function Login() {
  return (
    <Layout>
      <LoginForm />
      <br />
      <span className="text-sm font-medium text-gray-900">
        Don't have an account yet? <Link to="/signup">go to signup</Link>.
      </span>
      <br />
      <span className="text-sm font-medium text-gray-900">
        Forgot your password? <Link to="/request-password-reset">reset it</Link>
        .
      </span>
    </Layout>
  );
}

export function Signup() {
  return (
    <Layout>
      <SignupForm />
      <br />
      <span className="text-sm font-medium text-gray-900">
        I already have an account (<Link to="/login">go to login</Link>).
      </span>
    </Layout>
  );
}

export function EmailVerification() {
  return (
    <Layout>
      <VerifyEmailForm />
      <br />
      <span className="text-sm font-medium text-gray-900">
        If everything is okay, <Link to="/login">go to login</Link>
      </span>
    </Layout>
  );
}

export function RequestPasswordReset() {
  return (
    <Layout>
      <ForgotPasswordForm />
    </Layout>
  );
}

export function PasswordReset() {
  return (
    <Layout>
      <ResetPasswordForm />
      <br />
      <span className="text-sm font-medium text-gray-900">
        If everything is okay, <Link to="/login">go to login</Link>
      </span>
    </Layout>
  );
}

// A layout component to center the content
export function Layout({ children }) {
  return (
    <div className="w-full h-full bg-white">
      <div className="min-w-full min-h-[75vh] flex items-center justify-center">
        <div className="w-full h-full max-w-sm p-5 bg-white">
          <div>{children}</div>
        </div>
      </div>
    </div>
  );
}
```
</TabItem>
<TabItem value="ts" label="TypeScript">

```tsx title="src/pages/auth.tsx"
import {
  LoginForm,
  SignupForm,
  VerifyEmailForm,
  ForgotPasswordForm,
  ResetPasswordForm,
} from 'wasp/client/auth'
import { Link } from 'react-router-dom'

export function Login() {
  return (
    <Layout>
      <LoginForm />
      <br />
      <span className="text-sm font-medium text-gray-900">
        Don't have an account yet? <Link to="/signup">go to signup</Link>.
      </span>
      <br />
      <span className="text-sm font-medium text-gray-900">
        Forgot your password? <Link to="/request-password-reset">reset it</Link>
        .
      </span>
    </Layout>
  );
}

export function Signup() {
  return (
    <Layout>
      <SignupForm />
      <br />
      <span className="text-sm font-medium text-gray-900">
        I already have an account (<Link to="/login">go to login</Link>).
      </span>
    </Layout>
  );
}

export function EmailVerification() {
  return (
    <Layout>
      <VerifyEmailForm />
      <br />
      <span className="text-sm font-medium text-gray-900">
        If everything is okay, <Link to="/login">go to login</Link>
      </span>
    </Layout>
  );
}

export function RequestPasswordReset() {
  return (
    <Layout>
      <ForgotPasswordForm />
    </Layout>
  );
}

export function PasswordReset() {
  return (
    <Layout>
      <ResetPasswordForm />
      <br />
      <span className="text-sm font-medium text-gray-900">
        If everything is okay, <Link to="/login">go to login</Link>
      </span>
    </Layout>
  );
}

// A layout component to center the content
export function Layout({ children }: { children: React.ReactNode }) {
  return (
    <div className="w-full h-full bg-white">
      <div className="min-w-full min-h-[75vh] flex items-center justify-center">
        <div className="w-full h-full max-w-sm p-5 bg-white">
          <div>{children}</div>
        </div>
      </div>
    </div>
  );
}
```
</TabItem>
</Tabs>

We imported the generated Auth UI components and used them in our pages. Read more about the Auth UI components [here](../auth/ui).

### 5. Set up an Email Sender

To support e-mail verification and password reset flows, we need an e-mail sender. Luckily, Wasp supports several email providers out of the box.

We'll use the `Dummy` provider to speed up the setup. It just logs the emails to the console instead of sending them. You can use any of the [supported email providers](../advanced/email#providers).

To set up the `Dummy` provider to send emails, add the following to the `main.wasp` file:

<Tabs groupId="js-ts">
<TabItem value="js" label="JavaScript">

```wasp title="main.wasp"
app myApp {
  // ...
  // 7. Set up the email sender
  emailSender: {
    provider: Dummy,
  }
}
```
</TabItem>
<TabItem value="ts" label="TypeScript">

```wasp title="main.wasp"
app myApp {
  // ...
  // 7. Set up the email sender
  emailSender: {
    provider: Dummy,
  }
}
```
</TabItem>
</Tabs>

### Conclusion

That's it! We have set up email authentication in our app. 🎉

Running `wasp db migrate-dev` and then `wasp start` should give you a working app with email authentication. If you want to put some of the pages behind authentication, read the [auth overview](../auth/overview).

## Login and Signup Flows

### Login

![Auth UI](/img/authui/login.png)

### Signup

![Auth UI](/img/authui/signup.png)

Some of the behavior you get out of the box:
1. Rate limiting
  
  We are limiting the rate of sign-up requests to **1 request per minute** per email address. This is done to prevent spamming.

2. Preventing user email leaks
  
  If somebody tries to signup with an email that already exists and it's verified, we _pretend_ that the account was created instead of saying it's an existing account. This is done to prevent leaking the user's email address.

3. Allowing registration for unverified emails

  If a user tries to register with an existing but **unverified** email, we'll allow them to do that. This is done to prevent bad actors from locking out other users from registering with their email address.

4. Password validation

  Read more about the default password validation rules and how to override them in [auth overview docs](../auth/overview).

## Email Verification Flow

:::info Automatic email verification in development

In development mode, you can skip the email verification step by setting the `SKIP_EMAIL_VERIFICATION_IN_DEV` environment variable to `true` in your `.env.server` file:

```env title=".env.server"
SKIP_EMAIL_VERIFICATION_IN_DEV=true
```

This is useful when you are developing your app and don't want to go through the email verification flow every time you sign up. It can be also useful when you are writing automated tests for your app.
:::

By default, Wasp requires the e-mail to be verified before allowing the user to log in. This is done by sending a verification email to the user's email address and requiring the user to click on a link in the email to verify their email address.

Our setup looks like this:

<Tabs groupId="js-ts">
<TabItem value="js" label="JavaScript">

```wasp title="main.wasp"
// ...

emailVerification: {
    clientRoute: EmailVerificationRoute,
}
```
</TabItem>
<TabItem value="ts" label="TypeScript">

```wasp title="main.wasp"
// ...

emailVerification: {
    clientRoute: EmailVerificationRoute,
}
```
</TabItem>
</Tabs>

When the user receives an e-mail, they receive a link that goes to the client route specified in the `clientRoute` field.  In our case, this is the `EmailVerificationRoute` route we defined in the `main.wasp` file.

The content of the e-mail can be customized, read more about it [here](#emailverification-emailverificationconfig-).

### Email Verification Page

We defined our email verification page in the `auth.{jsx,tsx}` file.

![Auth UI](/img/authui/email_verification.png)

## Password Reset Flow

Users can request a password and then they'll receive an e-mail with a link to reset their password.

Some of the behavior you get out of the box:
1. Rate limiting
  
  We are limiting the rate of sign-up requests to **1 request per minute** per email address. This is done to prevent spamming.

2. Preventing user email leaks

  If somebody requests a password reset with an unknown email address, we'll give back the same response as if the user requested a password reset successfully. This is done to prevent leaking information.

Our setup in `main.wasp` looks like this:

<Tabs groupId="js-ts">
<TabItem value="js" label="JavaScript">

```wasp title="main.wasp"
// ...

passwordReset: {
    clientRoute: PasswordResetRoute,
}
```
</TabItem>
<TabItem value="ts" label="TypeScript">

```wasp title="main.wasp"
// ...

passwordReset: {
    clientRoute: PasswordResetRoute,
}
```
</TabItem>
</Tabs>

### Request Password Reset Page

Users request their password to be reset by going to the `/request-password-reset` route. We defined our request password reset page in the `auth.{jsx,tsx}` file.

![Request password reset page](/img/authui/forgot_password_after.png)

### Password Reset Page

When the user receives an e-mail, they receive a link that goes to the client route specified in the `clientRoute` field. In our case, this is the `PasswordResetRoute` route we defined in the `main.wasp` file.

![Request password reset page](/img/authui/reset_password_after.png)

Users can enter their new password there.

The content of the e-mail can be customized, read more about it [here](#passwordreset-passwordresetconfig-).

## Creating a Custom Sign-up Action

:::caution Creating a custom sign-up action

We don't recommend creating a custom sign-up action unless you have a good reason to do so. It is a complex process and you can easily make a mistake that will compromise the security of your app.
:::

The code of your custom sign-up action can look like this:

<Tabs groupId="js-ts">
<TabItem value="js" label="JavaScript">

```wasp title="main.wasp"
// ...

action customSignup {
  fn: import { signup } from "@src/auth/signup.js",

  sendEmailVerificationEmail,
} from 'wasp/server/auth'

export const signup = async (args, _context) => {

  ensurePasswordIsPresent(args)
  ensureValidPassword(args)

  try {
    const providerId = createProviderId('email', args.email)
    const existingAuthIdentity = await findAuthIdentity(providerId)

    if (existingAuthIdentity) {
      const providerData = deserializeAndSanitizeProviderData(existingAuthIdentity.providerData)
      // Your custom code here
    } else {
      // sanitizeAndSerializeProviderData will hash the user's password
      const newUserProviderData = await sanitizeAndSerializeProviderData({
          hashedPassword: args.password,
          isEmailVerified: false,

</Tabs>

We suggest using the built-in field validators for your authentication flow. You can import them from `wasp/server/auth`. These are the same validators that Wasp uses internally for the default authentication flow.

#### Email

- `ensureValidEmail(args)`

  Checks if the email is valid and throws an error if it's not. Read more about the validation rules [here](../auth/overview#default-validations).

#### Password

- `ensurePasswordIsPresent(args)`

  Checks if the password is present and throws an error if it's not.

- `ensureValidPassword(args)`

  Checks if the password is valid and throws an error if it's not. Read more about the validation rules [here](../auth/overview#default-validations).

## Using Auth

To read more about how to set up the logout button and how to get access to the logged-in user in our client and server code, read the [auth overview docs](../auth/overview).

### `getEmail`

If you are looking to access the user's email in your code, you can do that by accessing the info about the user that is stored in the `user.auth.identities` array.

To make things a bit easier for you, Wasp offers the `getEmail` helper.

#### `userSignupFields: ExtImport`

<UserSignupFieldsExplainer />

Read more about the `userSignupFields` function [here](./overview#1-defining-extra-fields). 

#### `fromField: EmailFromField` <Required />
`fromField` is a dict that specifies the name and e-mail address of the sender of the e-mails sent by your app. 

It has the following fields:
- `name`: name of the sender
- `email`: e-mail address of the sender <Required />

#### `emailVerification: EmailVerificationConfig` <Required />
`emailVerification` is a dict that specifies the details of the e-mail verification process.

It has the following fields:
- `clientRoute: Route`: a route that is used for the user to verify their e-mail address. <Required />

  Client route should handle the process of taking a token from the URL and sending it to the server to verify the e-mail address. You can use our `verifyEmail` action for that.

  <Tabs groupId="js-ts">
  <TabItem value="js" label="JavaScript">

  ```js title="src/pages/EmailVerificationPage.jsx"
  import { verifyEmail } from 'wasp/client/auth'
  ...
  await verifyEmail({ token });
  ```
  </TabItem>
  <TabItem value="ts" label="TypeScript">

  ```ts title="src/pages/EmailVerificationPage.tsx"
  import { verifyEmail } from 'wasp/client/auth'
  ...
  await verifyEmail({ token });
  ```
  </TabItem>
  </Tabs>

  :::note
    We used Auth UI above to avoid doing this work of sending the token to the server manually.
  :::

- `getEmailContentFn: ExtImport`: a function that returns the content of the e-mail that is sent to the user.

  Defining `getEmailContentFn` can be done by defining a file in the `src` directory.

  <Tabs groupId="js-ts">
  <TabItem value="js" label="JavaScript">

  ```ts title="src/email.js"
  export const getVerificationEmailContent = ({ verificationLink }) => ({
    subject: 'Verify your email',
    text: `Click the link below to verify your email: ${verificationLink}`,
    html: `
          <p>Click the link below to verify your email</p>
          <a href="${verificationLink}">Verify email</a>
      `,
  })
  ```
  </TabItem>
  <TabItem value="ts" label="TypeScript">

  ```ts title="src/email.ts"
  import { GetVerificationEmailContentFn } from 'wasp/server/auth'

  export const getVerificationEmailContent: GetVerificationEmailContentFn = ({
    verificationLink,
  }) => ({
    subject: 'Verify your email',
    text: `Click the link below to verify your email: ${verificationLink}`,
    html: `
          <p>Click the link below to verify your email</p>
          <a href="${verificationLink}">Verify email</a>
      `,
  })
  ```
  </TabItem>
  </Tabs>

  <small>This is the default content of the e-mail, you can customize it to your liking.</small>


#### `passwordReset: PasswordResetConfig` <Required />
`passwordReset` is a dict that specifies the password reset process. 

It has the following fields:
- `clientRoute: Route`: a route that is used for the user to reset their password. <Required />

  Client route should handle the process of taking a token from the URL and a new password from the user and sending it to the server.  You can use our `requestPasswordReset` and `resetPassword` actions to do that.

  <Tabs groupId="js-ts">
  <TabItem value="js" label="JavaScript">

  ```js title="src/pages/ForgotPasswordPage.jsx"
  import { requestPasswordReset } from 'wasp/client/auth'

  ```ts title="src/email.js"
  export const getPasswordResetEmailContent = ({ passwordResetLink }) => ({
    subject: 'Password reset',
