We use LastPass at work as well, don't understand why they perform search so poorly, the search you can do on the text field is really unusable, in the plugin it works better, but if I select an entry, en then instead of keeping the plugin open, it closes so I have to search it again for the OTP, such poor UX
I can't replace it because it is the corporate standard at work.
The UI seems to work against me. Search? Don't even bother, better off with just your eyeballs. Refresh? No, try logging out and back in.
There are better alternatives, both when it was chosen and now, but it wasn't my decision to make.
