What LessPass is

LessPass is a free, open-source password manager that generates a password from a website, login, and master password instead of storing a synchronized vault. It can calculate passwords offline, so its method does not require syncing a vault between devices or to the cloud. Web settings include character choices, password length, a counter, and options for removing subdomains or top-level domains. Chrome and Firefox extensions can copy generated passwords to the clipboard, while listed mobile applications cover iOS, Android, and F-Droid. A command-line version can be installed with pip and used in a terminal. LessPass is licensed under GNU GPLv3 and recommends browser extensions for security reasons. New LessPass Server registrations are closed; users who want connected use must self-host a server. The project cautions that alternative server implementations may not fully support the latest API. The website identifies Guillaume Vincent as founder and directs questions to GitHub issues or [email protected].

As lesspass.com lists them, read 12 Oct 2026. The maker's own page has the final word.

Verdict

LessPass takes a stateless approach: passwords are derived when needed rather than kept in a synchronization database. Its broad platform coverage and open-source license are balanced by the need to self-host for new connected-server use.
