Your public display name is the name that appears publicly, for example on your posts and comments.
You can change your display name as many times as you want with these steps:
- Open the My Site tab.
- Tap the person icon to open the "Me" screen.
- Open the My Profile section.
- Tap on "Display Name."
- Enter the name you want to use.
When you go back to the "Me" screen, you'll see your new display name above your username at the top of the screen.
