+
+GNOME Keyring for managing secrets, SSH keys, and application passwords.
+
+## Installation
+
+```bash
+sudo pacman -S gnome-keyring libsecret seahorse
+```
+
+- `gnome-keyring` — The keyring daemon
+- `libsecret` — Library for apps to access secrets
+- `seahorse` — GUI for managing keyring
+
+## PAM Integration
+
+Automatically unlock keyring on login.
+
+Edit `/etc/pam.d/login`:
+```
+auth       optional     pam_gnome_keyring.so
+session    optional     pam_gnome_keyring.so auto_start
+```
+
+For GDM/SDDM, also edit `/etc/pam.d/passwd`:
+```
+password   optional     pam_gnome_keyring.so
+```
+
+## Hyprland Integration
+
+Add to `~/.config/hypr/hyprland.conf`:
+```bash
+exec-once = gnome-keyring-daemon --start --components=secrets,ssh
+```
+
+Set environment variables in hyprland.conf:
+```bash
+env = SSH_AUTH_SOCK,$XDG_RUNTIME_DIR/gcr/ssh
+```
+
+Or in your shell profile:
+```bash
+export SSH_AUTH_SOCK="$XDG_RUNTIME_DIR/gcr/ssh"
+```
+
+## SSH Key Management
+
+### Add key to agent
+
+```bash
+ssh-add ~/.ssh/id_ed25519
+```
+
+### List keys
+
+```bash
+ssh-add -l
+```
+
+### GUI management
+
+Launch Seahorse:
+```bash
+seahorse
+```
+
+## Unlocking
+
+If keyring doesn't auto-unlock:
+
+```bash
+# Manually unlock
+gnome-keyring-daemon --unlock
+
+# Or via secret-tool
+secret-tool search --unlock xdg:schema org.gnome.keyring.Note
+```
+
+## Application Support
+
+Apps using libsecret (most modern apps) will automatically use gnome-keyring. For apps that need explicit setup:
+
+### Git credential storage
+
+```bash
+git config --global credential.helper /usr/lib/git-core/git-credential-libsecret
+```
+
+### VS Code
+
+VS Code uses gnome-keyring automatically for settings sync.
