Final answer:
Federation improves user experience and security by allowing Single Sign-On across multiple services, while Password Vaulting securely stores and automates user credentials, complemented with extra layers like two-factor authentication.
Step-by-step explanation:
The choice between using Federation and Password Vaulting (Secure Web Authentication) is important for managing identity and access within an organization. Federation involves linking the identities from different systems, domains, or organizations to allow users to access multiple applications with one set of credentials. This offers numerous benefits, including a better user experience, as users have fewer credentials to remember, and IT has fewer passwords to manage, which can reduce the risk of password-related breaches. Moreover, federation often utilizes protocols like SAML, OAuth, and OpenID Connect that facilitate secure and streamlined Single Sign-On (SSO) capabilities.
On the other hand, Password Vaulting provides a different approach to secure authentication by storing user credentials for various services and automating the login process without the user needing to enter credentials each time. This method enhances security with the use of two-factor authentication and allows for the implementation of stronger password policies. While providing increased security, this also helps guard against phishing attacks as users are less likely to input credentials into fraudulent sites.
