SSO with Open Id

Hi everyone, I have been looking at different way to create an Single Sign On from scratch for various aaplications that I build in Mendix. All the aaplications have the user name and password. I found SSO can also be achieved by the use of Open Id. So, What is Open Id and how can I implement the SSO with Open ID? Do I have configure something in all the applications to support Open Id?

You can use Open ID but you would need an Identity provider(IdP)  to be able to use it unless you have your own server to do so. But if there is an IdP then I would choose SAML. Mendix has a good module to use SAML. Note that Microsoft is also able to use SAML so Office 365 clients can also use SAML.
