gauth

Fast, no-nonsense 2FA for your terminal, written in Go.

tl;dr

• gauth: Show codes (with color-coded countdowns)
• gauth -w: Watch mode (auto-refresh)
• gauth -a: Add new account
• gauth -d: Delete account
• gauth -l: List all accounts
• gauth -p: Manage master password (AES-256 encryption)
• gauth -i/-e: andOTP backup support
• Saves to $HOME/.gauth/gauth.json (atomic writes)
