Authentication_SSO < IVOA

---+ Authentication: Single-Sign-On (SSO)

Single sign-on authentication means that you login once to a VO site or service and can then access any other VO site or service without repeating the authentication process. Conventional wisdom is that this should be done with digital signatures, but the standards for these signatures allow many different approaches. A [[http://www.ivoa.net/Documents/latest/SSOAuthMech.html][specification for the authentication mechanisms]] that the VO should use is now an IVOA Recommendation.
