To protect your account from various attacks, we highly recommend that you use the following security features:
Two-factor authentication (2FA): after the initial setup, you will need to use the 2FA every time when making some important changes to your account.
Wallet lock: as a security precaution, it is possible to lock your current payout address so that it cannot be changed by anyone who gains access to your pool account.
Remember, you should never use the same password for multiple services as a security practice. You should also avoid using predictable passwords.
