Hello @jason18,
Welcome to the Auth0 community!
I understand that you might be having some trouble with MFA even though you did not set it up. This might be caused by an error or a bug.
In order to regain access to your account I suggest requesting an MFA reset. You can find a step by step explanation on how to do that in the following Knowledge Solution: Account Locked: MFA Resets Requests
I hope this was helpful and if you have more questions, don’t hesitate to come back to the community.
Thanks,
Tudor
