Of' course you know how important it is to use strong unique passwords for web accounts and to keep them secure. If you used to rely only upon your own brains - unfortunately, such strategy just can't be considered safe anymore. Nowadays there seems to be no better way than to change your passwords to real strong ones, which are, obviously, very hard to remember. However, this tool can help you with it.
This simple tool can turn your single secret gesture (or a master-password) into a particular password for any website you need. It's possible to make, using additional information you provide (the site name and, optionally, the hash salt) and a cryptographic hash function. Then, it puts the result right in an active input field in your open browser tab. Everything works in a fully autonomous manner on your device - it doesn't keep information neither locally nor sends it anywhere.
