I lost my access to Google Auth app and now, I can't sign-in to my Opera account.
I have my backup keys, I got them when I first opened two step auth setting.
When I enter my backup keys, it just says they are wrong.
I have my backup keys as a screen shot, so I'm sure there is not any misspelling etc.
I tried all 10 backup keys, with uppercase and lowercase too but it is same.
I can access my e-mail with no problem.
Can you guys help me?
