How to Protect Your Saved Passwords in Firefox with a Master Password

For better security, don't rely on browser synchronization to manage your passwords. Here is a better solution.


How to Protect Your Saved Passwords in Firefox with a Master Password

In a perfect world, you would never let a web browser save your passwords. Why? Because web browsers aren’t exactly the most secure software on your computer. To complicate matters, most modern browsers allow you to sync your passwords with an account, so they’re available to any browser associated with that account.

It’s not ideal for security.

You do not believe me? If you’re using the Firefox web browser (which is much more secure than, say, Chrome), open the browser, then go to Settings, then Privacy & Security, and click Saved Credentials.

What you are about to see may surprise you. You can scroll through the entire list and view any saved password by simply clicking the eye icon associated with the entry.

You’re not prompted for a password or anything else…you just get unrestricted access to all saved credentials.

What to do then?

What is a master password?

If you really want Firefox to save your passwords, you should protect them with a master password. Once you enable Master Password (formerly known as Master Password), you will be prompted to enter this password each time you open Firefox and each time you want to view a saved password.

The only thing you need to keep in mind is that if you forget this master password, you might be in trouble. To reset this password, you need to open Firefox, and go to chrome://pippki/content/resetpassword.xhtml, then click Clear. When you do this, everything you have backed up is lost.

So if you want to keep those credentials intact, it’s in your best interest not to lose that password.

How to protect your saved passwords in Firefox with a master password?

Are you ready to configure this option? Let’s go.


The only thing you will need is an up-to-date version of Firefox. I recommend that you always keep your web browsers updated to the latest versions to avoid software vulnerabilities.

1. Open Settings

Open Firefox, then click the menu button (three horizontal lines) at the top right of the window. In the drop-down menu, click Settings .

2. Navigate to usernames and passwords

In the Settings window, click Privacy & Security in the left pane, then find Logins and Passwords .

3. Enable master password

Check the Use master password box . A pop-up window will then appear. Enter and verify your master password. You will also see a very clear warning about remembering the master password. Heed this warning and write down your master password (preferably in a password manager).

4. Click OK to set your master password

Click OK and your master password will be set. Now whenever you launch Firefox or attempt to view a password, you will be prompted to enter that password.

Congratulations, you’ve added a welcome layer of security to Firefox. Now the only person who can see your saved passwords is you
