It doesn't really work for me: it's as if it locks up but, actually, it's because, on my phone, it takes an inordinate amount of time (over 3 minutes) to generate a password. So, I use My LessPass instead, which is much quicker for me (at about 6 seconds).
For those confused about what this app does: it's a password manager that doesn't save any data. The username, master password, and website name are mashed together with math to create a super-secure password. It will always generate the same password as long as those 3 parameters don't change. The emoticons on the right let you verify if you typed in the right password (using the same math-mashing technique), but you'll have to wait a second or so before it shows the actual emoticons. Otherwise it'd be possible for a shoulder-peeker to guess the password character-by-character instead of all at once, with the former being trivial and the latter impossible. It also lets you set parameters for the password and a "counter", which lets you generate way more passwords with the same input if you need to change your password somewhere.
Well after setting this app up online, it does not take my master password anymore and the password reset function does not work either. There are no support links on the site just Twitter accounts which I think is pathetic.
Perfect solution, thanks!
