What is a Master Key?
Last updated: July 3, 2026
A Master Key is an additional security feature you can enable that allows you to:
- •
Prevent an unwanted password reset, even if your email account is compromised (if enabled, the Master Key is required to reset your Kraken sign-in password).
- •
Use it as an alternative method for Sign-in Two-factor Authentication (2FA).
- •
Turn off the Global Settings Lock (GSL) immediately if enabled on your account.
We recommend setting up a Master Key in combination with other security features.
REMINDER
The Master Key should be kept separate from account sign-in information or any other 2FAs, as storing this information together would create a security threat to your account.
For example, if you use a Hardware Security Key for sign-in 2FA, we advise to then use an authenticator app or a different Hardware Security Key for the Master Key.
