 Can you answer the question, what is an ID token? ID tokens are used in OpenID Connect and ID tokens contain information about what happened when the user is authenticated and is intended to be read by the OAuth client. ID tokens may contain information about the user like the email address or username, but that is not a requirement of an ID token. When a user authenticates using an OpenID Connect provider and they get access to a web application, an ID token is issued and that ID token is passed to the application as proof that the user has been authenticated. You can also use ID tokens as a way to customize a user's experience. Since ID tokens can have information about a user, you can take information from that ID token and display it on the webpage with like a custom welcome message or just saying happy birthday on their birthday. Now you know what an ID token is and this has been Identity in a Minute.
