What authorization protocols do you know?

Main authorization protocols:

• OAuth 2.0 — a widely used protocol for delegated authorization, allowing applications to obtain limited access to user resources without transmitting passwords.
• OpenID Connect — an extension over OAuth 2.0, adding authentication and user information transfer.
• SAML (Security Assertion Markup Language) — an XML-based protocol for exchanging authentication and authorization data between parties, often used in corporate systems.
• Kerberos — a network authentication protocol using tickets to confirm identity.

Each of these protocols addresses authorization tasks in different scenarios, from web applications to corporate systems and services.
