Custom User ID Assignment with Actions , Early Access
UpdateUnverifiedAdded Sep 24, 2026
You can now assign a custom `user_id` to new database-connection users at signup by calling the `api.user.setUserId()` method in a `pre-user-registration` Action. Previously, Auth0 automatically generated user IDs in the standard `auth0|<id>` format for new signups.
