import Tabs from '@theme/Tabs';

Updates user data, if there is a logged in user.
```js
const { user, error } = await supabase.auth.update({email: 'new@email.com'})
```
## Parameters
-
attributes
required
UserAttributes
No description provided.
## Notes
User email: Email updates will send an email to both the user's current and new email with a confirmation link by default.
To toggle this behavior off and only send a single confirmation link to the new email, toggle "Double confirm email changes" under "Authentication" -> "Settings" off.
User metadata: It's generally better to store user data in a table inside your public schema (i.e. `public.users`).
Use the `update()` method if you have data which rarely changes or is specific only to the logged in user.
## Examples
### Update email for authenticated user.
Sends a "Confirm Email Change" email to the new email address.
```js
const { user, error } = await supabase.auth.update({email: 'new@email.com'})
```
### Update password for authenticated user.
```js
const { user, error } = await supabase.auth.update({password: 'new password'})
```
### Update a user's metadata.
```js
const { user, error } = await supabase.auth.update({
data: { hello: 'world' }
})
```
