Yubikey MF Authentication - Computer not trusted

Hello,

I have a YubiKey 4 (no NFC) and it works well with LastPass. One problem that I'm having now is that when I "trust" my home computer for 30 days, I still get prompted to authenticate with my Yubikey.

I had gone through 2 instances of trusting my PC, and it's worked for 30 days in both instances. Now, it will not trust my computer at all and I must authenticate with my Yubikey every time.

I have followed (without success) the instructions here: https://lastpass.com/support.php?cmd=showfaq&id=1853

When I log in, it seems to take for about 5 seconds, then punts me to the Yubikey authentication again. I will get a login error if I do not authenticate. In the short time before I get punted to the MF Authentication page, Lastpass *will* autofill in usernames and passwords, but then logs me out when I don't authenticate.

Any reason why the "Trust this device for 30 days" option isn't sticking? I even checked my account for "trusted devices" and see that my main PC is listed and active, but the MF authentication doesn't seem to care.

Thank you!

It's been doing the same thing for me.

Only doing it in Edge, not other browsers. I think it started happening right after the extension was last updated. Tried deleting the SUID file, but that didn't help.

Really irritating.

I'm having this same problem on multiple computers and multiple browsers - Chrome, Internet Explorer, Firefox. It won't work for me on anything anymore. I have used this feature successfully in the past (for a long time). Seems to have recently broken.

Same here. I have to re-auth every time I close the browser. 2 different PCs with firefox, same issue. Since this weekend, "trust this computer for 30 days" is not working anymore.

"Trust this computer for 30 days" for Yubikey is broken

Since the latest update (feb 5th), the option to "trust this computer for 30 days" is not working anymore. restarting the browser makes the PC untrusted.

See multiple users having the same issue here: viewtopic.php?f=12&t=323665

Add me to the list of people seeing this problem. But only a problem in Firefox (65.0.1 on Windows 10 1809), correct behavior in Chrome and Edge. I submitted a report but have not gotten any resolution yet.

Hi - me too. This is on Windows 10, using Edge. Restarting the browser forces re-authentication despite selecting the option to 'trust computer for 30 days'. Probably been this way for a few weeks (I didn't note the first time it happened) and I'd vaguely assumed that a fix would be imminent.

Thanks everyone for chiming in. I experience this problem with Chrome, but haven't tried it with Edge or Firefox. Based on feedback, looks like it's not unique to Chrome.

It's still a problem as of February 18, 2019 at 8:42 PM PST, for the record.

I'm also having this problem. It's happening on multiple computers (Windows 10). For me, Firefox works okay. But any Chrome based browser ignores the trusted device list. I have tried EVERYTHING to fix this. I've de-installed the browser and LP and then re-installed them. I've cleared the browser's cache. I've cleared out my trusted device list and recreated it from scratch. I also have the option enabled on LastPass to ignore the 30 day limit.

I've also made multiple support requests with LP. They always initially respond with having me do a few basic trouble shooting tasks. When I reply that those have not helped, they go into stealth mode and simply ignore my open support request.

This is very frustrating! I've been using LastPass Premium for 6 or 7 years. But, I think it's time to switch.
