Passphrase. Also known as teh 25th word.

[RGPankO]

I use no keys without passphrases.
Therefore I can not use Kraken wallet.

Why would I risk my assets with the single point of failure that if someone, by any chance, finds my seed phrase he would have access to my funds?
I ALWAYS use a 25th word to protect my assets.
Something that is easy for me to remember and I never write down.

This has to be implemented immidiatelly and related to my other issue that I posted - enabled for Power Users.
