# Remove a User

To remove a user, use the [DROP USER](https://docs.singlestore.com/db/v9.1/reference/sql-reference/security-management-commands/drop-user.md) command.

Similar to other user management operations, if you have `sync_permissions` enabled, log into the master aggregator as the `root` user or another user with sufficient permissions, and run:

```sql
DROP USER '<user>'@'<host>'

```

If `sync_permissions` is not enabled, then you must perform this operation on each aggregator in the cluster.
