@leocg probably nothing can be done now. When I set up two-factor authentication, I never thought that because of it I would lose access to my account ... Thank you for your answers and for your help.

@leocg tried 2fas apps, authy - wrong codes. I don't know what else I could install.

@leocg Why 12 characters, not 8? This is probably not the recovery backup code provided by Opera. I don't have another one.

@leocg I have a 12 digit backup code and I need 8 digits. This code doesn't work. My authentication code was saved on my computer at home, in Ukraine. And now I'm trying to log into my opera account from a laptop from the Czech Republic. Now I'm trying to install other authentication applications and try to log in through them. Didn't know the problem could be due to another authentication app.

@leocg I am using Google Authenticator. Unfortunately, I don't remember which authentication app I used to enable 2fa. But I think it's a google app.

@leocg yes, many times. idk why.

Hello. I'm trying to log into my opera account, but when I enter the two-factor authentication code, it says "invalid code", although I enter the code correctly and have tried many times already. I tried to change the password for the account, it still did not help - the two-factor authentication code is invalid. This is really my account, you can check all my details: email, phone number and more. Is it possible to disable this authentication altogether without logging into your account? Please help me to login to my account, help with this two factor authentication problem.
