If you want to use Messenger without Facebook, you can simply deactivate your Facebook account. This will remove all of your personal information from the Facebook servers, including your posts. Alternatively, you can upload your contact list to Messenger. Just make sure you explain to your friends that you're doing this temporarily.
Facebook Messenger is a great way to stay in touch with your friends and family. Before, you didn't have to have a Facebook account to use Messenger. It used to be possible to sign up with just your phone number, but the service gradually phasing this out. However, if you want to continue using the Messenger app, you must create a Facebook account.
Facebook Messenger used to allow you to sign up without a Facebook account, but this feature was discontinued by Facebook in 2019. Nowadays, you must have a Facebook account to use Messenger. This can be a bit of a hassle, especially if you're not sure about your privacy settings. However, this doesn't mean that you can't use Messenger. Just install the app and follow the instructions to sign up for Messenger.
Alternatively, you can also deactivate your Facebook account, which will log you out of the service. Once you've done that, you can then use Messenger. This method is recommended if you've accidentally deleted your Facebook account. This will prevent you from losing access to your messages. It's the safest way to use Messenger.
To deactivate your Facebook account, click on the "Deactivate Account" option in the left-hand column. Afterward, follow the on-screen instructions. Now, you'll have an account for Messenger, but you'll no longer have to worry about people searching for you on Facebook. However, you'll lose access to your profile picture and messages.
If you're not a Facebook user, you can still use Messenger if you use a compatible Android or iOS device. Using Messenger doesn't reactivate your Facebook account - only your contacts will be able to contact you through the app. As long as you keep the app updated, you can continue using it without being tied to Facebook.
There are a couple of hiccups you may encounter when using Messenger without Facebook. The first is that it's important to create a new Messenger account instead of logging into your existing one. You should delete your old account before you do the process. If you've already created an account with Facebook, you may experience a pop-up when you log into the app.
