Is there a way to get backup codes? I enabled 2FA, but I donβt see anywhere to generate them.
I couldn't find backup codes but I was able to perform a password reset which logged me in and let me disable or reconfigure 2fa.
Seems strange that you could remove 2FA without being forced to authenticate via 2FA first.
As far as I can tell, no. There's no backup codes and there's no "verification" of the codes when you enable it.
Also, you do not get logged out of any other sessions even if they were logged in before 2FA was enabled.
So I typically leave my desktop browser logged in as a backdoor in case something goes wrong I can use that session to re-disable 2FA.
Then once I have verified it working on mobile I will sign out the desktop browser and sign it back in with the 2FA key.
But yeah, no backup codes. Apparently an admin can disable 2FA on your account if you get locked out, or so I have heard.
You may want to add a warning to your post. For instances that don't require an email address, it's currently quite easy to get permanently locked out of your account because the code is never verified.
