To take on other popular messaging apps, including WhatsApps that
rumours say Facebook is eyeing to buy, Facebook has enabled users to
create a Facebook Messenger account without a Facebook account and using
only a name and phone number.
The new feature was added to the latest version of Facebook's
Messenger app for Android. This new log in ability is expected to come
to the Facebook Messenger app on other platforms as well.
The Facebook-free login for Messenger was made possible because the
Messenger app is used for private communication and is not dependent on
other Facebook public features such as the news feed and therefore
similar logins may not be extended to other apps such as the Facebook
Camera app.
