Is OAuth hackable?
An attacker can exploit this by registering an account with the OAuth provider using the same details as a target user, such as a known email address. Client applications may then allow the attacker to sign in as the victim via this fraudulent account with the OAuth provider.
Is OAuth PKI?

What is an OAuth key?
An OAuth token is like that valet key. As a user, you get to tell the consumers what they can use and what they can’t use from each service provider. You can give each consumer a different valet key. They never have the full key or any of the private data that gives them access to the full key.
Can a public key system be used for OAuth?
Public/Private key systems can be used to provide three kinds of services: Technically, none of the above three services are required for an OAuth system to work properly – it’s very possible to build an OAuth system which doesn’t use public/private keys for anything, at all.
How are OAuth tokens different from API keys?
Unlike with API keys, OAuth does not require a user to go spelunking through a developer portal. In fact, in the best cases, users simply click a button to allow an application to access their accounts. OAuth, specifically OAuth 2.0, is a standard for the process that goes on behind the scenes to ensure secure handling of these permissions.
Which is property 1 of an OAuth system?
That said, OAuth systems will often rely on property 1 of public/private key systems to ensure that OAuth related communication is encrypted, usually by building communication protocols on top of existing TLS/SSL based systems.
How to create a public / private key pair for okta?
We recommend generating the public/private key pair first before creating the OAuth service app. to generate a JWKS public/private key pair for testing. Okta supports both RSA and Elliptic Curve (EC) keys.
