Imagine you walk into a big party. You don’t know anyone, and no one knows you. But you have a name tag on. That name tag has your name, maybe where you’re from, and perhaps a fun fact about you.
Now, when you meet someone at the party, they look at your name tag and say, “Hi, [Your Name]! Nice to meet you.” That name tag helps them identify you in a crowd of strangers. If you come back to another party next week and wear the same name tag, people will remember you by looking at it.
In the world of computers and the internet, “user identity” is like that name tag. It tells systems who you are so that they can give you access to things you’re supposed to see, like your email, and keep out of stuff you shouldn’t, like someone else’s private messages.
So, whenever you log into an app or a website, you’re essentially putting on your digital name tag, letting the system know, “Hey, it’s me! Remember what I can and can’t do here.”
