OTPClient
OTPClient manages desktop TOTP and HOTP tokens with a GTK4 interface, QR and URI import, and command-line integration.
About OTPClient
OTPClient is an open-source desktop application for managing TOTP and HOTP two-factor authentication tokens. It has a GTK4 and libadwaita interface and can add tokens by scanning a QR code from an image file, the webcam, or the clipboard, or by entering the secret manually. Tokens can be kept in multiple encrypted databases, with cross-database search and optional grouping by label. A command-line tool (otpclient-cli) supports scripting, and a separate search provider integrates with GNOME Shell and KDE Plasma 6 KRunner.
Several features depend on the platform or build. Start-at-login is unavailable on some desktops in the Flatpak build, and start-minimized requires minimize-to-tray and a system tray. The --output-dir option is ignored in the Flatpak build.
