I remember a try and I couldn't integrate it to browser... is a standalone application isnt' it?
Why would you ever want to integrate it into a browser? The idea of security is to close as many avenues of attack as possible. I know they are all secure, but I'd never trust any data to "the Cloud."
the beauty of the thing is to be there when you need it to fill form, login, or save quickly and efficiently.
That's exactly what it does, and not just in web forms - I use it for SSH access, FTP, all sorts of non-browser apps. It's completely portable - wherever I am I can load the USB stick
and run the program directly from the USB. You right-click on the entry, select "copy password" (or user name, whatever) and switch to the appropriate app, paste, done. A bonus: when you copy from Keepass you can see a progress bar moving. You have ten seconds (configurable if you need more time) to paste after which Keepass completely flushes it from the clipboard, making it even more difficult for malicious wares to steal data.
Besides: what happen if someone picks up your pendrive? your passwords will be all compromised. How do you deal with that?
You might want to give it a deeper try - all data stored in the .kdbx databases are encrypted. It's completely useless to anyone who accesses it without the master password to open the database. You now only have to ever remember one password, ever again - and it's the one to access your Keepass database (or, a few passwords if you maintain multiple databases.)
I manage literally thousands of passwords. I set them, and forget what they are minutes later. I just copy/paste from Keepass. It's the real deal.
