LastPass Android app fails to authenticate with fingerprint

Exactly. Fingerprint works everywhere except LastPass pop up. Glad it works fine for most people. Worked fine for me for years, but no longer. Problem solved though, as I've now switched services.

I have the same issue on a OnePlus 8 Pro. Initially I thought the issue was the in-screen fingerprint reader but I now understand this is an issue just with LastPass - I can unlock my phone fine with fingerprint immediately after LP has failed to authenticate me.

This is something of a deal-breaker for me. When is this going to be fixed?

I should also add that the behaviour is intermittent - sometimes it works, sometimes not. Logging back in with the master password seems to get everything straight again.

It's been broken since December for me. I switched to BitWarden, recommend you bail as well. They have showed zero concern over this.

Same problem here. It started on my Pixel 3 and now I've upgraded to a Pixel 4a 5g I see exactly the same issue. It has persisted across Android upgrades. I can authenticate using my fingerprint within the LastPass app (and in other apps) but the LastPass pop-up doesn't work.

This is compounded by my frustration with the failure to properly implement FIDO/U2F security. I'm going to investigate the competition, starting with either Bitwarden or 1Password. I've heard good things about both of them, but I'm not about to jump ship in a hurry in case they have their own issues.

(FWIW, I'm the admin of a LastPass Enterprise account and have recommended it to multiple friends and family. If I move, then over time LastPass are likely to lose dozens of licenses - and if I manage to persuade my employer to roll out password managers globally, thousands of licenses.)

What is the best alternative for LastPass currently, with the most features free or paid and a working fingerprint unlock ?

Hey, welcome! I hate to tell you this but they have shown 0 care about fixing this problem. I had the issue since December. Jumped ship to BitWarden a couple months ago, which isn't as nice as LastPass when it worked. BW works though, and that is nice. Recommend you bail, as they've completely disregarded this issue and written us off.

My Premium account expires on January 29, 2022. I'll be onto 1Password by then. I suspect LastPass QA hasn't tried very hard to reproduce this problem so they don't take it seriously. Too bad. It's a fatal flaw on mobile.

Just wanted to say that they finally almost fixed the issue. Now when trying to fingerprint unlock for autofill, instead of an overlay, a lastpass window opens up and it does unlock successfully.

There is still a bug though, if you have an account protected by password (not lastpass, one of the saved accounts) and try to autofill in a new app, it will ask to unlock twice, first one for lastpass and second for the account, but at the end nothing will happen.  To fix this, remove the password protection from the account, try to autofill, it will prompt a message to confirm the autofill in this app and then it will work. You can enable the password protection back after this. The issue here is that confirm prompt not showing up when the password protection is enabled.
