This plugin allows administrators to login on October backend with a third party account (at the moment, Google accounts only).

Users will be able to login with current user / password credentials as usual.

All authentication attempts (Successful or Failed) are logged for extra security.

Backend login screen


  • Install plugin as usual.


  • Goto October backend
  • Browse to Settings > System > October Backend SSO Login
  • Read the documentation inside the configuration screen on how to create a project in Google Developers Console


  • Remember to update your backend user email address with the same Google account you plan to use for login
  • For new users, first create the administrator and assign the right email address, no user registration is done through this plugin
  • You must be running build 292 or newer

Possible errors

  • Class 'Google_Client' not found: the Google Api Client composer package is required, check vendor inside the plugin folder

    Works as expected. I have one little error with return url there was because of "//backend" url.
