How to Sync Instagram Contacts to Facebook Messenger
Keeping in touch with friends on all the social networks you share can be an organizational challenge. However, Facebook now makes this task a little easier by letting you transfer your contacts from Instagram to Messenger, which also syncs your Instagram and Messenger conversations. If you merge and move all your contacts from Instagram to Messenger, your username and Instagram account will also be visible to other users in your Messenger chats – so they can of course haunt your pets’ photos.
To connect these two services, launch Messenger on your phone and click on your avatar. From the list that appears, select People and then click Sync Instagram Account.
Putting the two together automatically adds everyone you chat with on Instagram to Messenger, which may or may not be what you really want to do. If you’re someone who tends to view the two as separate entities with separate “friends,” or you want your Instagram life to be as hidden as possible from your Facebook friends, this isn’t for you.
