Love using it and works great!

Genz·27 Jul 2026

The latest version fixed a long-existing problem of the extension hanging both Firefox and Chrome. One of the best free cross-platform password managers and it stands out with the feature of prompting for the master password before populating your login credentials, which makes the extension more secure than most. It also includes features such as storage of payment card details for which others will charge you a premium. Yes, it doesn't detect the fields for login credential on some websites 100% of the time but that's not a deal breaker for me. And no, it doesn't come with integrated tokens for 2FA but that's what I prefer. Placing everything in one basket could just create a single point of failure. Other reviewers are correct too that the extension logs you out periodically. Most of the time, you only need to re-enter the master password. At other times, you will need to log in from scratch using your Norton account before getting to the vault - you do have the option to sign in using your Norton Passport Manager app on your phone though. That's not a bug but an expected and welcomed security feature for your protection. Have been using this probably since it first came out eons ago and I'll be sticking with it as my primary driver along with other vaults as backup.
