Thanks for reaching out to the Auth0 Community!
I understand that you are looking for a way to revert the user’s email address to your original email address.
To do so, you will need to update the user with the original email address by calling the Update a User endpoint.
Alternatively, you can accomplish the same results by changing the email address on the user profile page in the Auth0 Dashboard > User Management > Users > YOUR_USER and pressing the Actions > Change Email option.
In regards to your observations, I have tried the following:
- Update user’s email address to new email address
- Login using the new email address without verifying the new email address
- When trying to log in I received the Wrong email or password message.
And this is to be expected, and the correct error message. I could not get the brute force detection error message to throw, which reads Your account has been blocked after multiple consecutive login attempts.
If this error does occur, it most certainly involves Brute-Force Protection.
Hoped this helps!
Please let me know if you have any other questions. I’d be happy to help.
Thank you.
