@slytheringirl I had to upgrade my copy of Opera (which I had been avoiding because I despise what Opera has become over the past 2-3 years) as well as reset my sync data to get Opera to let me sign in. This sadly seems to be a permanent occurrance/issue with sync since the devs no longer care to listen to their users and actually fix sync. It's a shame really since Opera is the only browser (after Dolphin killed their Firefox extension years ago) that did sync properly at first, now it's as bad as all the others with syncing to android.
@slytheringirl The message was really from Opera? It could a phishing attempt.
And the fact that you got a message saying that someone attempted to reset your password doesn't mean that Opera was hacked but that someone that knows your email tried to use it to get a new password.
@leocg Hello, this is still me. So, in my desperation I looked into my folder that has a bunch of text files backed up, lo and behold, there was an "Opera backup codes" text file. Popped in the code, and deactivated 2 Factor Verification.
Although, I will say this, with the ease of setting up of 2 Factor Verification, there should be even more precautions taken. Like this whole "You lose the phone, you lose the account lol" system is so silly. Like what's the need of linking an account then, how is it different from just "Device 2 Step Verification". Very dumb system. Just a glorified/bluetooth "Device verification". If I had formatted my laptop, instead, or somehow had my data wiped (Without having backed up those codes) I would've been completely locked out. I got lucky this time.
But none of this is even remotely your fault, just wanted to put it out there.
Have a nice day,
and thanks for the help.
P.S. Google never even bothered to warn me about backing up my account in the Authenticator app. Or had done it automatically, either.
