Just to clarify: You're talking about Lastpass here? For myself, Lastpass has just been an absolutely terrible user experience, with many of the issues you're talking about. I have this obscure ritual I have to go through when generating new site passwords -- like generate one in a new tab, then go manually "add site" and input the information -- because Lastpass can't get it together.

Thats exactly what I do for generating a new password.

LastPass always thinks I want to replace credentials for subdomain sites. all the time.

When I have a password saved for foo.com And then I try to save a password for bar.foo.com. LastPass, for all that is holy and good in the world, stop assuming I want to replace my password for foo.com damnit.

maybe the ui is not great, but as far as I know you are asked every time (in a not very visible way that probably defaults on replacing the previous): if I'm not mistaken if you look at the very bottom of the save dialog/page there should be a dropdown that allows you to create a new entry

Yeah, LastPass. I sometimes copy and paste the auto-generated password just in case it loses it. I've had many occasions where it would flat out drop it after I save the site and now I have to immediately password reset because the password is nowhere to be found.

Yeah, I have had the same experience. I always end up copying the generated password.

This and the respondents' experiences below have been my experience too. If they can't get the basic UX right, I doubt they got the security right (they didn't: http://lifehacker.com/lastpass-hacked-time-to-change-your-ma...) and I'm not sticking around to find out. I switched to Enpass instead.

Would love to find an alternative that works for larger teams vs being meant for one individual at a time. LastPass has that functionality, big part of why we use it.
