In some countries though, there is permission to create a Facebook Messenger account without having a Facebook account. The Facebook messenger application is available for mobile phones like iPhone, Android phones, and Windows phones and amazingly it can also be accessed from the official Messenger website on your computer. Aside from chatting with friends, Messenger allows you to make free voice and video calls, chat with chatbots, and also send and receive money.
Steps to Sign into Facebook Messenger: When you launch Messenger, you’ll be prompted to log in. If you already have Facebook installed on your device, you can quickly log in with the same Facebook account.
