Hi @umar,
Thanks for reaching out to the Auth0 Community!
I understand you have a blocked end-user that you would like to unblock.
To unblock the user, you’ll need to go to your Auth0 Dashboard’s User Management > Users and find the blocked user. Open their profile, and click on the Actions button on the top right, and unblock the user for all IPs:
Once that is complete, the user will be unblocked and can resume logging in again.
Please let me know if you have any further questions.
Thank you.
