@leocg said in Can't log in to git Hub:

@frido82 Right, you clearly didn't understand what I said, let me try again.

If you use an extension or a flag to change Opera's user agent into Chrome or Firefox ones, do you see any difference?

Tested Chrome and Firefox in windows, same result (see attachment).

@leocg when i use Chrome and Firefox i can login succesfully to git hub, but if i try with opera, using the same credential i get the error that i mentioned.

@leocg I got login success with firefox and chrome.

Opera version 76.0.4017.123
still can't login to github either if password is correct.
Github shows the message that the username/password is wrong but is due to a problem in the browser.
Solution: use Chrome, Firefox or other.
