Exam SY0-601 topic 1 question 699 discussion

This is OpenID. It's using sign-in credentials from OTHER popular websites. An example of this would be logging into CompTIA using a google/gmail account. OpenID uses SSO. However, SSO is more broad and I feel OpenID perfectly fits this scenario.

OpenID is an open standard that allows users to authenticate with various websites using a single identity provider, such as Google, Facebook, or Microsoft. This way, users do not need to create and remember multiple usernames and passwords for different websites. OpenID also gives users more control over their personal information and privacy. SSO(Single Sign-on) is a similar concept to OpenID, but it is usually implemented within a specific domain or organization, such as a company or a school.

it's D. the reason why A is not right, becasue SSo doesn't necessarily increase the user base.

SSO stands for Single Sign-On, which is a technology that allows users to log in to multiple websites using a single set of credentials, such as a username and password or a digital certificate. SSO eliminates the need for users to create and remember multiple accounts and passwords for different websites, and simplifies the authentication process. SSO also enhances security by reducing the risk of password reuse, phishing, and identity theft.

D. OpenID

While they are similar and essentially accomplish the same goal SSO and OpenID have different scope and implementation in practice. With SSO you just need to enter your credential ones and then the access to applications and systems are seamless, you don't need to provide your credentials again. That makes it a good choice for enterprise environments were employees need to switch from one application to another and it saves time to use SSO . On the other hand OpenID needs you to identify yourself every time you access some application by asking you the enter your credentials.

i believe SSO is implemented in an enterprise level to access all the apps and services once authenticated, makes it easier to access all apps and services on the fly that enterprise uses. Whereas, OpenID is more of allowing users to log in to multiple websites or services using a single set of credentials, and the login is usually not bound to authenticate inside the enterprise, it authenticates any websites or services thats part of the federation.

OpenID is an open specification for authentication and single sign-on (SSO)

SSO for sure
