What is it?

LessPass generates passwords on demand from a login, the website name, and a master password. Because the passwords are derived rather than stored, there is no encrypted vault to back up or synchronize across devices. You only need to remember the master password to get the same password on any device.

It is available as a browser extension for Chrome and Firefox, a command line interface installable with pip, and a mobile app for iOS and Android. A web-based generator is also provided, though the project recommends the extensions for better security.

The project is licensed under GPL-3.0, with the mobile package additionally available under MPL 2.0. Optional server features are limited to existing users, and the project notes that new users must self-host a server to use connected functionality.
