Official site for KeePass. KeePass is an open source password manager. I have good belief that this software is legitimate and is not stealing your info (especially since it is open source. You can check the code yourself if you have the knowledge). The site has advertisements (that, luckily, do not attempt to annoy the user), but they have to keep the lights on somehow
Having trouble remembering all your passwords? Trying to improve your on-line security by using a different password on each site? Give Keepass a try and let it remember your passwords for you. I've been using it for years. Great program and even better price - free!
