Hashpass

It's a Dashlane like? (http://www.producthunt.com/posts...)

I made Hashpass because it's hard to memorize lots of passwords, and I don't like the idea of storing passwords in a proprietary database format + relying on a third-party tool to open it. Unusual for a password manager, Hashpass never writes anything to disk. Instead, it uses a simple formula to deterministically generate passwords, so there is nothing to sync and nothing to lose. You only need one secret key, so it's convenient—but it's also a single point of failure. More info on the tradeoffs: https://github.com/boyers/hashpass

I like the concept, but I am afraid that because of all the security breaches, you would end up with too many keys overtime.
