Note, using "Login with Wordpress" requires that your Wordpress site has an appropriate OAuth2 Server plugin to allow the
Wordpress site to work as an authorization server. vBulletin only acts as the "client" and uses the tokens and data generated by
the Wordpress's plugin in order to create, link and/or authenticate vBulletin users with Wordpress's user data.


====Gathering required data (Client ID & Secret, Endpoints)====
This depends on the specific plugin being used on your Wordpress site, but generally OAuth2 server plugins will have the following
items that are auto-generated:
 Client ID - usually some kind of string hash
 Client Secret - usually some kind of string hash
 Authorization (Auth) Endpoint - URL
 Token Endpoint - URL
 Resource Endpoint - URL -- Also called Profile, User [Data], or Me, depending on the specific plugin.
 Scopes - Space separated list of tokens/words, like "id email" -- You shouldn't have to specify these separately out of the
          default values.

Furthermore, you will likely have to fill this bit in:
 Callback or Redirect URI -- This value should be set to {your vbulletin frontendurl}/oauth2/callback



===Enable WordpressLogin in vBulletin===
Log into your forum's AdminCP.
Go to "Products & Hooks" > "Manage Products" and enable "Third Party Login - Wordpress" if it's not already enabled.
Click on the "Related Options: Enable Sign-in with Wordpress" link to go to the options link.
In the options, Enable Sign-in with Wordpress & enter the name of the Wordpress site, its URL, and the client id & secret that was
generated by the OAuth2 Server plugin on your Wordpress site.
Also enter the relevant Endpoint URLs.
If you want, you can also specify a custom logo URL to use with the sign-in / connect buttons.
Save the options.
