How are these open-source password managers and security tools chosen?

Apps come from desktop awesome lists (Awesome Linux Software, awesome-mac, awesome-windows, awesome-electron and the media and file sections of awesome-cli-apps), more than 70 GitHub topics such as desktop-app, electron-app, tauri-app, gtk, qt, macos-app, pdf-editor, cad and remote-desktop, and a hand-picked list of flagship apps. An app is listed only if it has a license (one GitHub detects, or one appsgit checked by hand), a README and a commit in the last six months, is not archived or a fork, and has 1000+ GitHub stars (topics), 500+ (awesome lists) or 100+ (hand-picked). It must also be an end-user application with a desktop signal: installers in its releases, install instructions for Windows, macOS or Linux, or a Flathub, Homebrew, winget, Chocolatey, Snap or AUR package. Libraries, frameworks, themes, plugins and servers are left out, and source-available apps are labelled as such.
