Okay kiddo, do you know what a passport is? It's like an ID that lets you go to different countries. An e-pass is kind of like that but for electronic things like the internet.
When you go online and use different websites, sometimes you have to put in your username and password. An e-pass is a way to make that process easier by letting you use just one username and password for many different websites.
Think of it like a special key that unlocks lots of doors. With an e-pass, you don't have to keep track of lots of different usernames and passwords for each website you visit.
It's also a way to keep your information safe. Only you know your e-pass username and password, so it helps prevent other people from getting into your accounts.
Overall, an e-pass is just a convenient way to access lots of different websites online without having to remember a bunch of different usernames and passwords.
