For new applications created after August 5, 2025, the allowlist and blocklist will only apply to sign ups. Previously, these lists affected both sign ups and sign ins. For existing applications, your settings remain unchanged, but you can opt in to the new behavior anytime from the Clerk Dashboard under Settings > User & Authentication > Restrictions.

Why the change?

The allowlist and blocklist are designed to control who can create accounts, not manage existing users. Because blocking sign ins does not affect existing sessions, it was a half-measure to blocking access and often caused confusion. It also made challenging to block access to identifiers moving forward, without affecting existing accounts. If you need to completely revoke a user's access, you should use the ban feature instead, which will immediately end their active sessions and prevent them from signing in again.
