Random Password Generator

RPG is a tool for generating human-readable passwords.

If RPG crashes after an update from the App Store, delete its previous settings by running the following command in Terminal:
rm -Rf ~/Library/Containers/de.rwth-aachen.hci.rpg

  • Passwords are generated from syllables, numbers, and symbols
  • Syllables can be capitalized to enhance security at a very low cost for the user.
  • Symbols are picked from the iPhone's first (Symbols 1) and second (Symbols 2) keyboard layout to allow quick entry on your mobile phone.
  • Certain characters can be excluded from the password generation process to avoid typographical similarities (l vs. I)
  • For each password a secure hash (SHA-1) is generated consisting of 40 HEX characters, which can be used for extra strong passwords.
  • A minimized version of the RPG window stays on top of other applications to aid password entry where copy&paste is not available
  • Passwords and Hashes can be generated via the Services Menu from other applications (enable in System Preferences, Keyboard)

Install as a Service

RPG can be installed as a service that allows you generate a password anywhere via the context menu. To enable the service, open the Keyboard page of System Preferences and activate 'Generate Password' in the Services section of the Keyboard Shortcuts tab. Here, you can also configure a keyboard shortcut.
