An organization uses several hosted platforms for different tasks and wants users to sign in once, then be recognized on these platforms. Which approach meets this goal and prevents multiple copies of user details in each environment?
Maintaining a local database on each platform
Generating a unique static token per service
Asking for new credentials every time users switch tasks
A central system using cross-domain tokens is effective because it allows a single authority to confirm identities. This prevents separate credential databases in each platform and streamlines account management. Keeping user information in each environment or requiring multiple logins does not provide a unified experience. Assigning a static token to every service also fails to provide a common authority to easily revoke or update credentials.
