I'm really sorry to hear you're continuing to have the same issue.
There are a few possibilities for why this might happen, it would be best to have you open a support ticket so we can examine your account securely, in depth.
You can open a new support ticket here: https://support.kraken.com/hc/en-us/requests/new
We look forward to assisting you.
Same issue with the other account now...
I really believe something bigger is going on on your side of the 2FA.
I WILL create a new ticket and will get the same answer again "bla bla" new 2FA code. However I find this repeating issue quite concerning.
Lol. Now the 2FA code worked. I do suspect this has something to do with a time issue. But since this happens to me only with kraken, is there any chance you are having some time sync issues serverside?
