After resetting my password, I have been trying to log into my Kraken account for countless times,
Don't do this next time, their damn system is tracking and counting failed logins even if it's their system fault so it wouldn't be a surprise to end up getting your account locked for security reasons, and funny enough is their system not telling this and keep giving you the generic answer you're receiving and when you finally log in you have suspended withdrawals, and support will take its sweet time enabling it again.
Also, if you're cleaning cookies and using a different machine, try to leave at least 15 minutes before the last action and the new try, don't know the rationale behind it but that's what support told me when I asked if this will happen again after resetting the password.
