`ALTER USER ... WITH PASSWORD` sets a user's password.

---

## Syntax

```questdb-sql
ALTER USER userName WITH PASSWORD password;
```

## Description

Setting a password replaces any existing one. Empty passwords are rejected, so
`WITH PASSWORD ''` cannot be used to clear one; use
[`WITH NO PASSWORD`](/docs/query/sql/acl/alter-user-with-no-password/) instead.

## Examples

```questdb-sql
ALTER USER john WITH PASSWORD '1m@re@lh@cker';
```

Verify with:

```questdb-sql
SHOW USER john;
```

| auth_type  | enabled |
| ---------- | ------- |
| Password   | true    |
| JWK Token  | false   |
| REST Token | false   |
