If you are having issues connecting with Facebook, you may need to set up an app password for Trillian within the Facebook settings. Once set up, you can use this app password instead of your main Facebook password to connect.
Trillian supports optional connectivity with Facebook Messenger, allowing you to pull down your existing Facebook Messenger contacts to send and receive instant messages. You must have an existing Facebook account to leverage these features!
Connecting to Facebook Messenger
Click the Trillian button in the upper left of your contact list and click Settings:
Click the IM Accounts section, click Add a new account, and click Facebook:
Type your existing Facebook email and password and click Connect.
What ports are required to connect to Facebook Messenger?
Facebook Messenger uses TCP/443.
How do I sign into Facebook Messenger if I'm using two-factor authentication?
After you sign in and receive a bad password error, simply plug in the current 2FA code as your password and try again and you should be signed in. You will need to do this every time you sign into Facebook Messenger.
