it is actually easy to use, quite the opposite of

https://addons.mozilla.org/de/firefox/addon/keycat/reviews/?score=1

However, we cannot tolerate a 1-line-documentation with next to zero content. So here is the ersatz-documentation: Aprico is one of thousands of pw-managers using the same idea:

- just derive all passwords from a seed + domainname. example: JimmyID and RT.com yields key 95768057896 reproducibly

- this means: NO SERVER whatsoever - which is a good thing - and where http://key.cat breaks down so pathetically of course.

- however, aprico is clearly more tedious than the firefox-builtin password-manager, but kinda acceptable. So contrary to the 1-liner, you have already found a pw-manager more easy than this: it is the firefox built-in password manager!

As long as the author leaves us with this sick joke of a documentation no higher rating than 2 stars is possible. after more clicking some more meaningful documentation appears, but the 1-liner is still a joke. Well OK, begrudgingly I give it 4 stars, since the author clearly has put in more effort into docs than most deliverers of AMO garbageWarez.

password managers are highly sensitive and MUST HAVE proper documentation without the usual Web jargon b.s..
