How to set up a master password in Firefox to protect saved data?

The master password in the Mozilla Firefox browser is a robust security tool that protects your saved accounts, usernames, and passwords from unauthorized access. If other people use your computer or the device has multiple users, this feature becomes an essential element of digital hygiene.

To set a master password, open the main browser menu, click on the three horizontal lines icon, and go to the settings section. In the left sidebar menu, select the Privacy & Security tab, then scroll down to the logins and passwords section.

Check the box next to using a master password. The system will open a new window where you will need to enter a complex combination of characters. Pay attention to the password strength indicator and try to use a unique combination of uppercase and lowercase letters, numbers, and special characters.

Once you confirm the entered password, the protection is activated instantly. The next time you launch the browser or the first time you attempt to autofill a login form on any website, Firefox will ask you to enter the master password to decrypt the database. Remember that it is impossible to recover a forgotten master password using standard methods, so it is best to write it down in a secure place.
