As a software engineer in a security product I've decided to take action and to create the ultimate & safest password manager.

I wanted a full control on my password's physical location without trusting third party servers or solutions (like LastPass, Roboform, etc).

I also wanted to add best practice security policies such as changing passwords frequently and alerting me on duplicated or non-strong passwords usage in websites.

In the meanwhile Passter evolved from your comments and suggestions, thank you.
