OpenID Connect is like a secret code that lets you access things on the internet without creating a new account or password each time. It’s just like a magic key that unlocks many doors without you having to remember different keys for each door.
So, when you want to use a website or an app that requires you to create an account and remember a password, OpenID Connect lets you log in using your existing account on another website or app.
For instance, you can use your Facebook or Google account to login to various other apps or websites instead of having to make a new account for each. This way, you don't have to remember a lot of passwords and usernames for different websites and apps.
OpenID Connect is like the middleman between the app or website you want to access and the account you already have, letting you easily connect and move between different online sites using just one identity.
