Security assertion markup language definition
Security assertion markup language (or SAML for short) is a way for different systems to securely exchange authentication and authorization information. It allows you to log in to one system and then access other systems without needing to log in again. This helps make online experiences smoother and more secure.
How SAML works
- When you try to access a service or application, the service sends an authentication request to the identity provider (IDP) asking if you're who you say you are.
- The IDP checks your identity and sends back a response with authentication information, often in the form of a digitally signed token.
- If the IDP confirms your identity, the service grants you access without needing to ask for your password again.
- Throughout this process, all communication between the service and the IDP is encrypted, ensuring that your identity information remains safe.
Benefits of SAML
- Users can access several applications with just one login — so much easier than having to log in over and over again.
- SAML makes sure that authentication data is transmitted securely, making unauthorized access less likely.
- SAML simplifies user management by letting organizations control access centrally.
- SAML works with various systems for seamless integration between applications.
- The language is good for big companies because it can easily adjust to their needs as they grow.
