Using Master Password on Firefox for Android

Primary Password is replacing Master Password. Firefox is removing terminology from the browser that has been identified as derogatory or exclusionary. Learn more about why we’re making this change.

Firefox can save usernames and passwords that you use to access online services, such as banking and email. In order to prevent someone else from accessing your accounts if they have your device, you can set a master password. This article explains how to use a master password.

How does the master password work?

After you have defined a master password, you will be prompted to enter it when Firefox needs to access your stored passwords. This will "unlock" the usernames and passwords that you've saved and Firefox will automatically fill them in for you as you browse from website to website. When you are done using the web, you can quit Firefox to "lock up" your usernames and passwords.

Note: The Android system on your device may quit Firefox automatically to free up resources when you are using another app. If that happens, you'll be asked to enter your master password again when you switch back to Firefox.

How do I set up a master password?
