## Notes

- In order to use the `updateUser()` method, the user needs to be signed in first.
- Email updates will send an email to both the user's current and new email with a confirmation link by default.
  To only send a single confirmation link to the user's new email, you can toggle the "Secure email change" setting in [your project](https://app.supabase.com/project/_/auth/settings).

## Examples

### Update the email of an authenticated user

Sends a "Confirm Email Change" email to the new email address.

```js
const { data, error } = await supabase.auth.updateUser({
  email: 'new@email.com',
})
```

### Update the password of an authenticated user

```js
const { data, error } = await supabase.auth.updateUser({
  password: 'new password',
})
```

### Update the user's metadata.

```js
const { data, error } = await supabase.auth.updateUser({
  data: { hello: 'world' },
