One of the biggest reasons someone decides to use a password manager is to avoid having to remember every single password they make for a website, app, or service. The next biggest reason is so that they no longer have to type them out every time. However, in order to access the vault of information they store, they typically require some kind of a master password. That kind of defeats the purpose. LastPass is doing way with that.
The company is allowing users to unlock their vault using the LastPass Authenticator app (in case you don’t already have enough Authenticator apps installed). The app will allow users to unlock their vault using a random code through the app, skipping the need of having to enter a password.
Of course, this isn’t the perfect solution as it still requires you to enter something. Thankfully, the company isn’t done with developing this out. LastPass plans to also allow for other authentication options that also make use of FIDO2 compliance. This means that, eventually, you’ll be able to use your fingerprint as well as specific security keys like the YubiKey products.
Hopefully, some of the other options, like Dashlane or Keeper, follow suit with their own password-less logins to eliminate master passwords altogether. Dashlane does offer limited biometrics depending on the browser you are using. However, you will have to re-enter your master password every 14 days or less (depending on if you delay it for the full 14 days each time or not).
