pwgen

pwgen is a simple self-hosted web app for generating secure passwords or passphrases with customizable options. It lets users choose random passwords or word-based passphrases and keeps generation on infrastructure they run themselves.

It can include uppercase letters, digits, and special characters, exclude homoglyphs, and generate up to 5 results at once. Passphrases support capitalization, separators, numbers, special characters, and custom word lists from URLs or local files. Generated values can be copied to the clipboard, saved in a browser cookie, and checked against the haveibeenpwned API unless offline mode is enabled.

pwgen runs as a Docker web application and has a demo at pwgen.joonatanh.com. It supports English, Finnish, and French word lists, PWA behavior, environment variable defaults, and a language dropdown toggle. The project is open source under AGPL-3.0.
