Single sign-on (SSO) is an important cloud security technology that reduces all user application logins to one login for greater security and convenience. Single sign-on (SSO) is a technology which combines several different application login screens into one. With SSO, a user only has to enter their login credentials (username, password, etc.) one time on a single page to access all of their SaaS applications.
SSO is often used in a business context, when user applications are assigned and managed by an internal IT team. Remote workers who use SaaS applications also benefit from using SSO.
Imagine if customers who had already been admitted to a bar were asked to show their identification card to prove their age each time they attempted to purchase additional alcoholic beverages. Some customers would quickly become frustrated with the continual checks and might even attempt to circumvent these measures by sneaking in their own beverages.
However, most establishments will only check a customer’s identification once, and then serve the customer several drinks over the course of an evening. This is somewhat like an SSO system: instead of establishing their identity over and over, a user establishes their identity once and can then access several different services.
SSO is an important aspect of many identity and access management (IAM) or access control solutions. User identity verification is crucial for knowing which permissions each user should have. Cloudflare Zero Trust is one example of an access control solution that integrates with SSO solutions for managing users’ identities. Learn more in the Cloudflare Learning Center.
