About:
Keychain is a script that manages ssh-agent sessions efficiently. It allows you to reuse a single ssh-agent process across multiple login sessions, storing credentials securely in the system keychain. This eliminates the need to repeatedly enter passphrases while maintaining security.
Key Features:
  • Manages ssh-agent lifecycle automatically
  • Persists credentials across terminal sessions
  • Supports both SSH and GPG keys
  • Works with system keychains (macOS, Linux)
Use Cases:
  • Developers managing multiple SSH connections across terminals
  • Automated scripts requiring SSH access without manual passphrase entry
Alternatives:
  • ssh-agent – Native agent requires manual session management
  • 1Password CLI – Commercial solution with GUI integration
