A master password is required to unlock your password manager. As password managers use encryption to secure stored data, the master password is linked to your vault’s decryption key, which is needed to access the data stored in your vault. To keep bad actors from accessing your vault, you should set up a strong master password that is not easy to guess or crack. You should also change it periodically (such as once per quarter) to avoid being hacked. Pro tip: Set up two-factor authentication (2FA) to further protect your vault. This is an extra verification step that protects your data even if hackers managed to crack your password.
