Firefox for mobile can save usernames and passwords that you use to access online services, such as your online banking and email websites. In order to protect the access to your Internet accounts against those who might get your device, you can set a master password . This article explains how to set up and remove a master password.

Defining a master password

By default, Firefox does not use master passwords to protect stored credentials. To define a master password:

1. Swipe left and tap the Gear button to access your Firefox Preferences.
2. Scroll down to the Privacy & Security preferences and tap the Use Master Password check box.
   
   
3. Type a strong 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 to ensure that you, and only you, will be able to retrieve this secure information. The password must be entered twice to confirm that you can enter it consistently.
4. To set the master password, tap OK.

Removing the master password

You can remove your Firefox mobile master password at any time:

1. Swipe left and tap the Gear button.
2. Scroll down to the Privacy & Security preferences and tap the Master Password check box.
3. Type your master password into the entry field.
   
   
4. Click OK to remove the Master Password.

Forgot it?

If you can't remove your master password because you've forgotten it, reset it:

1. In the Firefox location bar, enter the following location chrome://pippki/content/resetpassword.xul and tap Enter.
2. The "Reset Master Password" page will appear. Tap the Reset button, to reset your master password.
