It's as much as a pain as you make it. For me if I keep it well organized I basically just forget that I have to login to things at work, I just click them and I'm in or I navigate and it's filled.

I can see how it might not be the solution you want for home but at work I'm just trying to get things done and that unfortunately involves a large number of passwords that can't easily be federated into an SSO like okta because they span businesses clients and companies. I don't understand the hate for LastPass, for me it just works (tm)
