the problem with my login is that the wrong login is written, but I did not change the login, it was saved in the browser and I went through it hundreds of times, 2fa included there is everything but no access, even advertising letters came until I took a screenshot of letters that came and mail
You need to adjust the 2fa app time in relation to your device and then you might be able to log into your account. And in general, do not use this 2fa nonsense under any circumstances. Perhaps in 2fa this setting is called "Sync time with Google". But I don't remember exactly how to do it. If your device is captured, 2fa will not help you.
FBC also asks you to provide a phone number if you have installed 2fa protection, but if the time setting is not configured correctly, then even after resetting 2fa you will still have a problem logging into your account, or maybe your account really doesn’t work anymore.
