Can I use OAuth for authentication?

OAuth is not authentication. It’s an authorization protocol, or, better yet, a delegation protocol. It’s for this reason that identity protocols such as OpenID Connect exist and legacy protocols such as SAML use extension grants to link authentication and delegation.

How do I authenticate with OAuth?

In general, OAuth authentication follows a six step pattern:

1. An application requests authorization on a user’s behalf.
2. The application obtains a Grant Token.
3. The client requests an access token by using the Grant Token.
4. The authorization server validates the Grant Token and issues an Access Token and a Refresh Token.

Why OAuth is required?

OAuth is a delegated authorization framework for REST/APIs. It enables apps to obtain limited access (scopes) to a user’s data without giving away a user’s password. It decouples authentication from authorization and supports multiple use cases addressing different device capabilities.

Which is better JWT or OAuth?

OAuth2 is very flexible. JWT implementation is very easy and does not take long to implement. If your application needs this sort of flexibility, you should go with OAuth2. But if you don’t need this use-case scenario, implementing OAuth2 is a waste of time.

What is OAuth 2.0 authentication in REST API?

OAuth2 is the preferred method of authenticating access to the API. OAuth2 allows authorization without the external application getting the user’s email address or password. Instead, the external application gets a token that authorizes access to the user’s account.

Where is OAuth used?

Do I need to use OAuth with JWT?
