An iOS implementation of zerostore by joseph346. This was made mostly for fun — I'm not a cryptogrography expert, and cannot vouch for the security of this project.
Includes an app extension for use in browsers.
To quote the original project:
The goal of this project is to serve as a proof-of-concept for a zero-storage password management system. This means that all the information needed to generate a secure, unique, per-site password can be kept in a user's head. In this way, users can eliminate password reuse without having to memorize multiple passwords or synch password databases between devices. A user should be able to go on any device with this program and have access to all of their passwords without having to import any data.
Fork/clone the repo, then navigate to the directory and run pod install.
