Once your VKontakte app is ready you’ll need to copy and paste the Application ID and Secure key to the VKontakte provider’s Settings tab. You can find the information at your VKontakte app’s Settings which you can reach from the left sidebar.

Username prefix on register

Whenever a new user registers with their VKontakte account they can get a custom prefix so you can easily identify them.

Fallback username prefix on register

Whenever a new user registers with their VKontakte account and we can not generate a valid username from the first name or last name, a random username will be generated. With this option they can get a custom prefix so you can easily identify them.
