ISSUE: two-factor authentication

There is no enable two-factor authentication button after deleting the previous key.
I need two-factorauthentication, and I can’t restore it.

Same here. I recently switched to a new phone and for two-factor authentication, I couldn’t transfer OpenAI from my old phone to the new one. So, I deleted the two-factor authentication from the settings, hoping to restore it on my new phone. However, now I no longer have that option.
