Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

Amazon Redshift will no longer support the use of Python UDFs after June 30, 2026. We will start enforcing it in phases. For more information on the details of Python end of life and migration options, see the blog post that was published on June 30, 2025.

SHOW USER LOCKOUT

Use SHOW USER LOCKOUT to audit which users are currently locked, determine whether each lockout was automatic or manual, and review recent failed-login activity before you unlock a user. Federated users aren't included. This command is available only to superusers. For more information, see max_failed_login_attempts.

Required privileges

To use SHOW USER LOCKOUT, you must be a superuser.

Syntax

SHOW USER LOCKOUT

Output columns

user_name

The name of the database user.

is_locked

Specifies whether the user is currently locked.

lock_reason

The reason the user was locked. The value is automatic when Amazon Redshift locks the user after reaching the failed-attempt threshold, or manual when a superuser locks the user with ALTER USER NOLOGIN. This value is null when the user isn't locked.

locked_at

The timestamp when the user was locked.

last_failed_at

The timestamp of the most recent failed login attempt.

failed_login_attempts

The number of consecutive failed login attempts.

locked_by

The ID of the user that locked this user. This value is null for automatic lockout.

The following example displays the lockout status for all password-based users:
