Same problem. Possible that I lost everything (entry in MS Authenticator plus backup codes) when my old smartphone crashed, but I really cannot remember that I activated 2FA at all. However, how can I get access to deactivate 2FA or delete the Opera account? Both is Impossible without Authenticator codes and backup codes. Is there ANY way to put a request?
@sgunhouse Thank you! How can I do that? I can send in the email + password of the account if necessary + my attempts at getting in from the last 2 years,,
@Rcrmd Go to auth.opera.com while logged of or in a private window, type your email address and, in the next page, use the tool to create a new password.
@auroraplayzyt From where the device is supposedly connecting? And what is the time of the connection? Does it match with any of your logins to your Opera account?
