Rounding out the list of popular sites to use for authentication, we also support X. The directions below will get you up and running quickly. Sign in to the X Developer Console and create an app for your organization. Give it a name and description people will recognize, since they see them when they sign in.Add each login page that shows the X button to the app’s callback URLs. Rock sends the page’s full address, including the port, and X only accepts an exact match, so enter it the same way (for example, https://rock.rocksolidchurchdemo.com:443/page/3).Copy the app’s API Key and Secret (X also calls them the Consumer Key and Secret). Rock signs in with OAuth 1.0a, so you won’t need the OAuth 2.0 Client ID or Client Secret. Enter the key and secret in Consumer Key and Consumer Secret under Admin Tools > Settings > Authentication Services > Twitter, turn on Active and select Save.Let the app request email addresses. Rock asks X for each person’s email when they sign in and uses it with their name to find their existing person record. If X doesn’t share an email or no record matches, Rock creates a new person record with a Pending status the first time someone signs in with X.Open the block settings of the Login block on each login page and add Twitter to Secondary Authentication Types. The login screen then shows a Sign in with Twitter button. Intro to External Authentication lists the default login pages.
