Messenger, an instant messaging service from Facebook, was launched in August 2011 and replaced Facebook Chat. You can use Messenger without a Facebook account, so it is available to people who have not signed up or closed their accounts. While the two are partially connected, if you have a Facebook account, you don't have to have one.
The 5 Facebook Messenger Features You Need to Know
Messenger can be used with Facebook on your computer, at Messenger.com, or by opening the mobile app on Android and iOS devices. Since Messenger works on iPhones, it also works on Apple Watch.
You can also install add-ons in some browsers for faster access to Messenger. These are not official Facebook apps; they are third-party extensions that non-Facebook developers have released for free. For example, Firefox users can install the Messenger for Facebook add-on to put Messenger on the side of their screen and use it while browsing other websites in a split-screen mode.
At its core, Messenger is a texting app for both one-on-one and group messaging, but it can also send images and videos. It also has lots of built-in emojis, stickers, and GIFs.
