The general method for creating a social media profile is the same regardless of the social media site:
Update login (not shown) is visible if VSys is unable to log into your social media account. Use this link to re-log into the account so that VSys can use that account again.
You can use the Test link to have VSys test your authentication "token" to ensure that it's still functional and hasn't expired. If the token has expired, VSys will prompt you to log in again.
The Forget login link tells VSys to "forget" the connection between this profile and your social media account. You can then use the Update login link to connect to another account.
