Quick Answer: When Should You Use OAuth?

Should I use OAuth for my API?

If not then most likely, you don’t need to implement OAuth.

But if your data is sensitive, such as private user data, then you need to put some sort of security layer on your API.

Also, using OAuth or other token based security can help you build a better permission checking across your user base..

How does OAuth 2.0 authentication work?

It works by delegating user authentication to the service that hosts the user account, and authorizing third-party applications to access the user account. OAuth 2 provides authorization flows for web and desktop applications, and mobile devices.

Is OAuth better than SAML?

OAuth is more tailored towards access scoping than SAML. Access scoping is the practice of allowing only the bare minimum of access within the resource/app an identity requires once verified. For instance, OAuth is often used when a web app requests access to your system’s microphone and camera.

What is the difference between SAML and OAuth?

SAML (Security Assertion Mark-up Language) is an umbrella standard that covers federation, identity management and single sign-on (SSO). In contrast, the OAuth (Open Authorisation) is a standard for, colour me not surprised, authorisation of resources. Unlike SAML, it doesn’t deal with authentication.

What is the purpose of OAuth?

OAuth doesn’t share password data but instead uses authorization tokens to prove an identity between consumers and service providers. OAuth is an authentication protocol that allows you to approve one application interacting with another on your behalf without giving away your password.

Why OAuth is bad for authentication?

Let’s start with the biggest reason why OAuth isn’t authentication: access tokens are not intended for the client application. When an authorization server issues an access token, the intended audience is the protected resource. After all, this is what the token is providing access to.
