Hi there! A signature tag is like a special way to write your name on something. It's like when you write your name on a birthday card or a school assignment, but it's digital on a computer. When you write your name on a piece of paper, you use a pen or pencil to make the letters. But when you want to put your digital signature on something, you use a computer program to make it look like your signature.
This is important because it helps show that you are the one who made or agreed to something online. It can also help keep important things secure by making sure that nobody else can pretend to be you and sign things in your name.
When you use a signature tag, you're basically making a special code that identifies you as the person who wrote or signed something. It gets put into the computer file along with whatever you wrote or signed. Then, when somebody else looks at the file, they can see that code and know that it was actually you who signed it.
So there you go – a signature tag is like a digital way to make sure people know that something came from you, and only you!
