The Firefox Password Manager securely stores the usernames and passwords you use to access websites and then automatically fills them in for you the next time you visit. Even though the Password Manager stores your usernames and passwords on your hard drive in an encrypted
format, someone with access to your computer can still see or use them. The use of a master password
to protect stored usernames and passwords can prevent this and keep you protected in the event your computer is lost or stolen.
After you've set a master password, it needs to be entered the first time you remember a new password
or remove passwords
and each time you show your saved passwords
of sites, for each Firefox session.
By default, Firefox does not use master passwords to protect stored credentials.
This tutorial will show you how to create, change, or remove a master password
to protect your sensitive information such as saved passwords of websites stored on the Windows PC.
