> I have yet to find a case where my pwd manager fails to do this (lastpass). I've also never (with the default settings) had a site reject a password generated by it.

A few minutes ago I registered to T-mobile, and 1Password thought that my username was something like mytmobile.aspx. I also find that 1Password has a very hard time with banking sites. There is at least one bank where it simply fails to login. YMMV of course.

Going beyond these anecdotes, even if these heuristics almost always work, I believe that having heuristics involved at all is preventing mainstream adoption. I think that if the password management interface is standardized and heuristic-free, then we will see password management support in the mainstream browsers. I am imagining a future where the auto-generated passwords work transparently so that users don't even know about them. I think this cannot happen without browser support.

I agree that password management on mobile is a greater pain point, and (as mentioned elsewhere in this thread) the additional problem there is with entering the master password.
