## Introducing Prettier for docs
Prettier [was originally disabled for our docs as it didn't support MDX
2.0](1fa636417f),
outputting invalid MDX syntax.
This has since been fixed - prettier now supports MDX 2.0.
## Reducing print width
This also reduces the print width for the docs folder from 100 to 70.
Our docs code field are very narrow - this should help make code more
readable.

Payload offers the ability to [Authenticate](./overview) via JSON Web Tokens (JWT). These can be read from the responses of `login`, `logout`, `refresh`, and `me` auth operations.

**Tip:** You can access the logged-in user from within [Access
|
|
Control](../access-control/overview) and [Hooks](../hooks/overview) through
|
|
the `req.user` argument. [More details](./token-data).

### Identifying Users Via The Authorization Header
|
|
|
|
In addition to authenticating via an HTTP-only cookie, you can also identify users via the `Authorization` header on an HTTP request.
|
|
|
|
Example:
|
|
|
|
```ts
|
|
const user = await fetch('http://localhost:3000/api/users/login', {
|
|
method: 'POST',
|
|
body: JSON.stringify({
|
|
email: 'dev@payloadcms.com',
|
|
password: 'password',
|
|
}),
|
|
}).then((req) => await req.json())
|
|
|
|
const request = await fetch('http://localhost:3000', {
|
|
headers: {
|
|
Authorization: `JWT ${user.token}`,
|
|
},
|
|
})
|
|
```
|
|
|
|
### Omitting The Token
|
|
|
|
In some cases you may want to prevent the token from being returned from the auth operations. You can do that by setting `removeTokenFromResponse` to `true` like so:
|
|
|
|
```ts
|
|
import type { CollectionConfig } from 'payload'
|
|
|
|
export const UsersWithoutJWTs: CollectionConfig = {
|
|
slug: 'users-without-jwts',
|
|
auth: {
|
|
removeTokenFromResponse: true, // highlight-line
|
|
},
|
|
}
|
|
```
