Does anyone use these apps? What do you think …

Specifically the password generator, but I have used a few others and I like them. It all looks legitimate to me and they’re open source, but I’m not skilled enough to verify the code myself. So I’m just wondering if anyone else uses these and what are your thoughts?

I use LastPass for all my passwords, but I am considering using the password generator app from this website for some of my more important accounts. I’d create a master password, save it on LastPass, and then use that password to generate my account passwords via the password generator app. It would be a little more work, but sometimes I am not having all my passwords on LastPass is the best idea, at least this way if my LastPass account was compromised I would still be the only one who could generate the actual account passwords. Thoughts?
