Online identity

Online identity is like an identity card for the internet - it's how you prove who you are online. It's like your digital signature. When you join a website or an online game, you usually have to give them some kind of personal information, like your name and email address. That information is used to create an online identity for you, so that the website or online game knows who you are. This can also help keep your information safe, since only you know your online identity.
