Benefits of using a password manager

icon-s-light_illustrative_multiple-shields-svg

Enhanced security

Your security is our priority at LastPass. Local, zero-knowledge encryption for the password vault secures your data by storing it only on your device.

Time-saving convenience

Keep your data within arm’s reach at all times. LastPass features like save and autofill, plus storage for secure notes, lets you access your data with one tap of your finger to save you significant time.

Proactive control

We’ll always keep an eye out for you. Dark web monitoring auto-scans the web for compromised accounts while a 24/7 password strength tool assesses your password practices.

Is the Mozilla Firefox browser password manager secure?

Chances are, when using the Mozilla Firefox web browser, you’ve logged in to a website and Firefox has asked if you’d like to save it to their free password manager. While convenient, Firefox’s built-in password manager lacks security features essential to a password manager like LastPass.

For instance: a master password (what Firefox calls a Primary Password) is not essential to Firefox’s password manager. So, if your device ever gets stolen or hacked, all your login credentials and data are readily accessible to a bad actor. 

The LastPass password manager goes well beyond Firefox by providing additional security-minded features methods that heighten both safety and convenience.
