Use the Authorization Code flow with PKCE, and paste the entire response from the token endpoint in the box to check your work. (Note, only do this for accounts you've created specifically for this course, never paste access tokens from production systems in random websites!)

Parse the claims from the JWT using a Base64 decoder and paste the user's subject, name and email address into the form below. Remember that because you got this ID token over the back channel, you don't need to worry about verifying the JWT signature.
