What is the primary difference between OAuth 1.0 and OAuth 2.0?

  • OAuth 1.0 uses HMAC-SHA1 for signing requests, while OAuth 2.0 uses JWT.
  • OAuth 1.0 requires client registration, while OAuth 2.0 does not.
  • OAuth 1.0 uses two-legged authentication, while OAuth 2.0 uses three-legged authentication.
  • OAuth 1.0 is a token-based system, while OAuth 2.0 is a protocol for token-based authentication.
The primary difference is that OAuth 1.0 requires client registration, while OAuth 2.0 does not. OAuth 2.0 introduced a more streamlined and flexible approach to authorization. The other options describe differences but not the primary distinction.
