Using Master Password on Firefox for Android

This article is no longer maintained, so its content might be out of date.

This article is for an old version of Firefox for Android that's no longer supported. Please update to the latest version to get the most up-to-date features and fixes.

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?

By default, Firefox doesn't use a master password to protect your saved usernames and passwords. To set one up:

  1. Tap the Menu button (either at the bottom right on some devices or in the upper right of the browser) and then Settings (you may need to tap More first) .
  2. Then tap Privacy and choose Use master password.
  3. Type a password into the entry fields.
    Tip: Remember to make your password something that is easy for you to remember, but difficult for others to guess. See Create secure passwords to keep your identity safe to learn how.
  4. To set the master password, tap OK.

How do I remove a master password?

If you want to stop using a master password, you can easily remove it:

  1. Tap the Menu button (either at the bottom right on some devices or in the upper right of the browser) and then Settings (you may need to tap More first) .
  2. Then tap Privacy.
  3. Tap the Use master password check box.
  4. Type your master password into the entry field.
  5. Tap OK to remove the Master Password.

What can I do if I forget my master password?

If you've forgotten your master password, you'll have to reset it:

Warning: Resetting your master password will remove all of your saved usernames and passwords.
  1. Delete Firefox for Android data from Android Settings.
  2. The master password will be deleted and you'll be able to reset it.
