Pebble Authenticator (a fork of pTOTP) is meant to be used with another official & reliable authenticator. Do not make it the sole means of accessing your accounts.
While I have done my best to guard the credentials you enter in this application, I cannot guarantee that they will remain forever safe from prying eyes.
Nothing more than the standard Pebble 2.0 SDK is required to build and run this app. You may wish to change the configuration page URL in the showConfiguration event handler to point at a local development server.
