How to Create a Messenger Account Without Facebook
Open the Messenger app and tap Create a New Account. … A new browser window will appear, asking you to create a new Facebook account.
It is not possible to reactivate your Facebook account if you’ve deactivated it and still utilize Messenger. Only through the Messenger app or the chat window on Facebook may your friends contact you. You can download Facebook Messenger for iOS, Android, or Windows Phone.
You may now manage more than one Messenger account on the same device.
There’s no built-in feature that tells you whether someone has blocked you on Facebook Messenger. You can determine that you’ve been blocked on Messenger, though, from the status emblem state of a message you’ve sent.
To use your Facebook account on Messenger, download the Facebook Messenger app to your Android or iOS device. Open the app and log in with your existing credentials. Select a name and phone number for your new account.
