OpenID vs OAuth: Understanding API Security Protocols
When it comes to digital identity, OpenID and OAuth are two peas in a pod, but they have their differences. OpenID connects you to relying parties using a single sign-on, while OAuth grants access tokens so you can give apps limited access. They both make authentication simple, seamless, and secure. However, don't be fooled: behind the scenes, they're as different as night and day. OpenID is about logging you in, while OAuth is all about letting apps in.
