The zero-day bug in Sign In with Apple actually had nothing to do with the OAuth or OpenID Connect part of the Sign In with Apple exchange, and very little to do even with JWTs. Let's take a closer look to see what actually happened.
We will be talking about 'The Many Flavors of OAuth' at @APIdaysGlobal San Francisco about #oauth2 and briefly covering identity layers #openidconnect #oidc and #IndieAuth. We have a few tickets to giveaway. Please register with code 'Soonhin' at https://www.apidays.co/sanfrancisco. See you!
