@leocg Why Opera does not accept any Authenticator code, I tried to activate it with two different app. Wow, this problem still exists.

@leocg Did you get any results?

@leocg Yes, I have done the same.

@leocg Same problem with 2FA Authenticator app!

@leocg
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.

@leocg Yes. 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

Hello @leocg Can you check why Opera does not accept authentication codes?

Even with a new account, I tried to activate two-factor authentication, but Opera does not accept the authentication codes!

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,

@rasta122 If you use Gmail, you can define a new account with the same email for Opera by putting a dot in the previous Gmail.
for example:
before: OperaForTest123@gmail.com after: Opera.ForTest123@gmail.com
