`AUTH` authenticates a client connection to Yugabyte YEDIS API.

## Synopsis

**`AUTH password`**

This command authenticates a client connection to YugabyteDB's YEDIS API.

YugabyteDB can be set up to require a password for clients to authenticate themselves. The password verification can be enforced by using the `CONFIG` command to set the intended password (See `CONFIG`).

YEDIS allows for multiple passwords (up to 2) to be accepted.

- If the given `password` matches with any of the server configured password(s), server returns the status string "OK" and begins processing commands from the authenticated client.
- If the given `password` does not match with any of the server configured password(s), an error is raised

## Return value

Returns a status string if the password is accepted. Returns an error if the password is rejected.

## Examples

```sh
$ CONFIG SET requirepass "yugapass"
```

```

$ AUTH "yugapass"
