No, I am talking about the google authenticator apps, not your Kraken account.

I said if you have multiple email on your phone and you are in now that one where your google authenticator backup i.e. not sync that may be cause you are sawing your Google authenticator empty.
2FA authentication means  even you put an password the Authenticator apps will give you one time password for log in it make more safer your account from the hacker. And in the mean time if you lost your authentitor apps, obviously you have to face issues while log in. But if you have done KYC then you can contact with the DATA(NID, Passports etc) of your kyc for recovering your account.
Rather than what I do for you, a suggestion to read this official article of Kraken : How to transfer authenticator app sign-in 2FA to a new phone (and bypass sign-in 2FA for a lost phone)
