Is there a way to update userIds in bulk? Some logins from an older system are using GUIDs and we would like to switch to using user’s emails as the primary login, but need to update the older logins to use email as well.
Hi @tkmogel,
Welcome to the Auth0 Community!
Unfortunately, there is currently is no way to bulk update users. In this case, you could use the Auth0 Management API Update a user endpoint to update those individuals’ user ID’s.
Alternatively, you could use a Rule or Action to update the user’s user_id post-authentication. This way, you can trickle the updates as the user logs into your app.
Please let me know if you have any questions.
Thank you.
