How to Store Passwords, Tokens, and Application Secrets in Linux

Typically, a password manager is recommended for storing authorization data in applications. However, this solution may not always be suitable due to the excess features it often includes.

Key Rack is a small open-source application that allows you to store and manage passwords and secrets on Linux with the Gnome shell.

However, you won't find many of the familiar features of password managers here. The application offers the bare minimum. What sets Key Rack apart from other alternatives is its support for system keys (which can be found on most modern Linux desktops) and Flatpak secrets.

Secrets (passwords, tokens, and similar attributes) are managed by a daemon usually called gnome-keyring-daemon. However, accessing Flatpak secrets is not such a straightforward task for applications. But Key Rack handles this well. It provides users with a stylish GTK interface, which, in turn, ensures quick access to all system secrets.
