By default, Firefox does not use primary passwords (formerly known as a master password) to protect stored credentials. To define a primary password:

• Click on the menu button to open the menu panel.
• Click Passwords.
• Click the Firefox Lockwise menu (three dots), then click Preferences

The Firefox Settings Privacy & Security panel will open to the Logins and Passwords section.

Put a checkmark next to Use a Primary password to open the Change Primary Password dialog.

Enter your primary password. The Password quality meter will indicate the difficulty of guessing your defined password. To create a quality password, your primary password should include the following:

• • At least one capital letter.
  • One or more digits.
  • At least one non-alphanumeric character, such as: @ # $ % ^ & * ( ).
  • You should also make sure to define your password in a way which is easy for you to remember, but difficult to guess for others. By doing so, you ensure that you, and only you, will be able to retrieve this secure information. For more information on choosing passwords, see Create secure passwords to keep your identity safe.

Enter the password a second time to confirm that you have entered it consistently.

To set the primary password, click OK. Close the about:preferences page. Any changes you’ve made will automatically be saved.
