Para entender el presente de OpenID les recomiendo leer este post de 37 Signals uno de los primeros en saltar a brindar apoyo a lo que parecía ser una solución de identificación unificada frente a la continua aparición de nuevos servicios online...
it just made things harder. Especially when people were having problems with the often flaky OpenID providers and couldn't log into their account. OpenID has been a burden on support since the day it was launched.
Pese a que OpenID es una idea interesante, no es una implementación distribuída segura y Sun es el primero en describirlo de un modo bastante claro:
OpenID is an untrusted protocol. Sun has no liability for what happens to any information you give to a third-party web site using this service. Most OpenID-enabled sites are genuine but some may be phishers or other rogues. Sun currently has no way of distinguishing the good sites from the bad. Do not use the OpenID@Work service for any high-value, critical, or Sun proprietary information.
Esa última línea es casi igual a la que uso como respuesta cuando alguien me dice ¿y si uso OpenID? ;)
