Join Keith Casey for an in-depth discussion in this video The purpose of scopes and claims, part of Web Security: OAuth and OpenID Connect.
- [Instructor] Before we dig into the OAuth grant types,…we need to understand one more set of terminology.…We've already talked about tokens,…but I glossed over some of the details…on what's in them and how to interact with them.…So, let's introduce two new terms:…scopes and claims.…First, let's talk about scopes.…Remember, OAuth is centered around the idea of…what are you allowed to do.…Or more properly, what am I allowing the application…to do on my behalf?…So, it's entirely about permissions.…So, a scope is simply a group of permissions…that a user can grant to an application.…
For example, GitHub has a delete repost scope…which allows an application…to delete a repository on the user's behalf.…On the other hand,…Twitter has a scope for allowing applications…to read your direct messages.…Now, the core of the OAuth specification…is very broad in what it allows for scopes.…In fact, when I say broad,…I mean that it's effectively undefined.…And like any good specification,…which allows things to be open to interpretation,…
