If you create an account with Facebook, your last name will be added to your profile but only visible when you match with someone, not when someone views your profile in Discover. Here's how to remove or change your last name on your Hinge profile:
1. In the Hinge app, tap Settings
2. Tap the Pencil Icon beneath your photo
3. Scroll down and tap Name
4. Tap on your last name to make changes
5. Tap the Back button
6. Tap Done to save your changes
Including your last name is entirely up to you, but many Hinge users find that it helps to create a more authentic and more accountable community.
