Security Assertion Markup Language standard

Security Assertion Markup Language (SAML) is an open standard that enables secure communication of authentication and authorization data between different parties, typically between an identity provider (like a login service) and a service provider (like a website). When you log in to a service using SAML, your identity is verified by the identity provider, which then sends a special message to the service provider confirming your identity. This allows you to access multiple services without needing to log in separately to each one, enhancing both security and convenience.
