The same thing has just happened to me on March 3, 2021.
Somehow they bypass 2FA and emptied the account.
Not 1 question or enquirer from Kraken, they just closed the door on me and said great news here is your account back.

Kraken is not safe, your funds are only protected by automated emails, no world class security team exists, and 24/7 support is a virtual assistant called kai. Total sham,
