I have used last pass premium for many years but recently so much basic functionality of a password manager has been removed that the browser add-on is more hassle than it is worth.
Last Pass seems more and more to emphasize 'Launching' sites through its interface. I never want to do this. I go to a site (through multiple paths) and then want to call on my password manager for my stored credentials. This basic workflow seems to be harder and harder with each release.
Commonly last pass will not correctly detect the site or fields in a login page due to some quirk of the websites design and that is fine. But last pass has made it increasingly difficult to get credentials out of it making it necessary to leave the web page, search for the site, edit it, show the password on screen and copy it to the clip board. This used to be some quick typing and a button press.
This add-on has gotten so bad that I am now investigating alternative solutions.
