Hi Peter VAN GLABEKE ,

If you are an admin of your org ,you can unlock the user by the following steps :

1. In the Admin Console, go to Directory > People.
2. In the left menu, select Locked Out.
3. Click a user name in the Person & Username column.
4. Click More Actions, and then click Unlock Account.

Hi @0oi6o (0oi6o)​,

Thank you for posting on the Okta community page!

I have done some research and you could follow the below documentation in order to unlock your account:

Additionally, if the above does not do the trick, I would recommend to reach out to your IT/HelpDesk department to unlock your Okta account.

I hope the above information is helpful!
