The username plugin wraps the email and password authenticator and adds username support. This allows users to sign in and sign up with their username instead of their email.

<Step>
|
|
### Add Plugin to the server
|
|
|
|
```ts title="auth.ts" twoslash
|
|
import { betterAuth } from "better-auth"
|
|
import { username } from "better-auth/plugins"
|
|
|
|
const auth = await betterAuth({
|
|
database: {
|
|
provider: "sqlite",
|
|
url: "./db.sqlite",
|
|
},
|
|
plugins: [ // [!code highlight]
|
|
username() // [!code highlight]
|
|
] // [!code highlight]
|
|
})
|
|
```
|
|
</Step>
|
|
<Step>
|
|
### Add the client plugin
|
|
|
|
```ts title="client.ts" twoslash
|
|
import { createAuthClient } from "better-auth/client"
|
|
import { usernameClient } from "better-auth/client/plugins"
|
|
|
|
const client = createAuthClient({
|
|
plugins: [ // [!code highlight]
|
|
usernameClient() // [!code highlight]
|
|
] // [!code highlight]
|
|
})
|
|
```
|
|
</Step>
|
|
<Step>
|
|
### Signup with username
|
|
|
|
To signup a user with username, you can use the `signUp.username` function provided by the client. The `signUp` function takes an object with the following properties:
|
|
|
|
- `username`: The username of the user.
|
|
- `email`: The email address of the user.
|
|
- `password`: The password of the user. It should be at least 8 characters long and max 32 by default.
|
|
- `name`: The name of the user.
|
|
- `image`: The image of the user. (optional)
|
|
- `callbackURL`: The url to redirect to after the user has signed up. (optional)
|
|
|
|
```ts title="client.ts" twoslash
|
|
import { createAuthClient } from "better-auth/client"
|
|
import { usernameClient } from "better-auth/client/plugins"
|
|
const client = createAuthClient({
|
|
plugins: [ // [!code highlight]
|
|
usernameClient() // [!code highlight]
|
|
] // [!code highlight]
|
|
})
|
|
// ---cut---
|
|
|
|
const data = await client.signUp.username({
|
|
username: "test",
|
|
email: "test@email.com",
|
|
password: "password1234",
|
|
name: "test",
|
|
image: "https://example.com/image.png",
|
|
})
|
|
```
|
|
</Step>
|
|
<Step>
|
|
### Signin with username
|
|
|
|
To signin a user with username, you can use the `signIn.username` function provided by the client. The `signIn` function takes an object with the following properties:
|
|
|
|
- `username`: The username of the user.
|
|
- `password`: The password of the user.
|
|
- `callbackURL`: The url to redirect to after the user has signed in. (optional)
|
|
|
|
```ts title="client.ts" twoslash
|
|
import { createAuthClient } from "better-auth/client"
|
|
import { usernameClient } from "better-auth/client/plugins"
|
|
const client = createAuthClient({
|
|
plugins: [ // [!code highlight]
|
|
usernameClient() // [!code highlight]
|
|
] // [!code highlight]
|
|
})
|
|
// ---cut---
|
|
|
|
const data = await client.signIn.username({
|
|
username: "test",
|
|
password: "password1234",
|
|
})
|
|
```
|
|
</Step>
|
|
</Steps>

## Configuration
|
|
|
|
The username plugin doesn't require any configuration. It just needs to be added to the server and client.
|
|
|
|
## Database Schema
|
|
|
|
The username plugin requires a `username` field in the user table. If you're using better auth migration tool it will automatically add the `username` field to the user table. If not you can add it manually.
|
|
|
|
```ts
|
|
const shcmea = {
|
|
user: {
|
|
username: {
|
|
type: "string",
|
|
unique: true,
|
|
required: false
|
|
}
|
|
}
|
|
}
|
|
```
