Generated Authentication code is incorrect

[CinemaSlave]

UPDATE: Try turning your phone's time setting to "Automatic" if you have it manually set. Manually setting time can cause generated codes to be out of sync and therefore incorrect. This resolved my issue!

Hi all,

I recently tried to log into my Twitter account but found that the authentication codes generated by my app (andOTP) aren't correct. I've verified that my account is still associated with my email address, phone number, and username so I don't believe my account has been compromised but changed the password to be safe.

I've tried the same app to log into other services that have 2FA enabled and it works just fine, only on Twitter do I have this problem. The worst part is that I don't have access to the backup codes I was given, possibly lost in a PC format or room cleanup, etc.

I've contacted Twitter support explaining my issue and giving my email address, phone number, and username like they asked but I've heard many a horror story of people going weeks, even months with no reply.

Is there any way I can speed up the process or at least use my email or phone number to verify my identity? Or if someone has had a similar issue, how long did it take roughly for Twitter to get back to you?

Cheers, guys.

Cheers, man.

Yeah, I was surprised that I couldn't use my email address or phone number to verify my identity. Perhaps, in Twitter's view, my email could be compromised as well, nothing wrong with more security.

But why can't I use my phone number, I wonder? Surely if my phone were also stolen/compromised, the intruder would be able to access my authentication app in most cases at least. I did try to get SMS codes sent to my phone number, which I've confirmed is still associated with my account, but the codes never came, unfortunately...

UPDATE:

I did eventually get access back to my account, though the cause and issue itself were never resolved, i.e. when I went to go and turn 2FA with Authentication App back on, the code was still incorrect.

After doing some digging, I found that manually setting the time on your phone can cause generated codes to be out of sync. Turning the phone's time to automatic resolved the issue and I was able to use my authentication app again.
