When I log into kraken, I add username and passwoird, all good.. then 2FA screen. I open Google Authenticator and nothing, just an illustration of a cat playing with a wool ball... i.e no codes...?
During the initial 2fa set up, after snanning the qr code provided by Kraken using your authenticator, you'll have to get the generated code from your authenticator and input it in Kraken and click 'confirm', only then is the process complete. Can you confirm that this is what you did, though i doubt it, i feel you made a mistake somewhere.
