<![CDATA[Two-factor authentication]]>Hello
After updating Opera, I noticed that I was logged out of my "Synchronization" account.
Now Opera does not accept two-factor authentication codes when logging in again!
I have already registered it in the Google Authenticator application.

Best regards,

Q1: Yes. / I tried with the latest version of Google Authenticator, but the codes are not accepted!
Q2: No!

My version of Google Authenticator is a bit old, but when I update it, the program stops working and "Unfortunately App has Stopped" message is show.

It's a new Google Authenticator installation? If so, then you lost access to your old account unless you have a backup code.

Even with a new account in Opera, I tried to activate two-factor authentication, and after scanning the barcode in Google Authenticator, Opera does not accept the codes.
My phone's Google Authenticator version is 5.10
