OTP Token Paster for OS X

An OS X service that enters the current one-time password (OTP) into the current iTerm window.

It doesn't overwrite the contents of the clipboard, and uses the OATH Toolkit's oathtool(1) to generate the token.

Using

• Install Homebrew
• brew install oath-toolkit
• If it isn't already present, enter secret=YOUR_BASE32_ENCODED_SECRET in ~/.JAuth.rc.
• mkdir -p ~/Library/Services
• Clone the repository.
• mv 'Enter Current OTP Token.workflow' ~/Library/Services
• Open System Preferences -> Keyboard -> Keyboard Shortcuts -> Services -> Enter Current OTP Token (probably way down at the bottom).
• Click 'add shortcut' and enter the key combination you want to use.

Caveats

The hotkey may not work until you go to the application menu in iTerm (click 'iTerm' in the menu bar) and point at the Services menu. You don't have to actually click any of the services; expanding the menu is enough to make OS X recognize the keyboard shortcut exists. You have to do this each time you run iTerm.

I'm guessing this is a bug in OS X, and displaying the Services menu forces it to load the service information.
