Security
Single Sign-On (SSO)
Also known as: SSO
Single sign-on lets users authenticate once with a central identity provider and access multiple applications without re-entering credentials, typically implemented with SAML or OpenID Connect.
The security benefit is centralised control: disabling one account revokes access everywhere, which manual per-application offboarding reliably fails to achieve.
SSO is frequently gated behind enterprise pricing tiers, a practice contentious enough to have earned its own name among buyers.
