About Pass Butler
Pass Butler is developed by Bastian Raschke from Hamburg living in Munich, Germany.
Security was always a topic that interested me, so I studied computer science with focus on “secure and mobile systems” at the University of Applied Sciences in Trier, Germany. In that time I developed a fingerprint sensor software, a hardware security USB dongle (inspired by the famous YubiKey) and a lot more technical devices.
Now in my full-time job I'm a professional Android developer working for more than 6 years (see my website), so I put my knowledge together to start building my own password manager in 2019 because the competitors lacked of features I needed:
I wanted a modern looking app with a self-hosted sync server (without external sync bridge) and unlimited password sharing backed by cryptography to avoid storing all my private passwords on my business devices (only some chosen passwords should be accessible). I also think it is unacceptable for an app that handles highly sensitive data like passwords to include ads, analytics or tracking, which many of the competitors do. So Pass Butler was developed with love and patience in nearly 3 years in my free time to provide an app that is well-engineered and offers high code quality to protect your valueable login credentials as good as possible.
