Single sign-on (SSO) allows users to access multiple applications with one identity. Implemented correctly, it improves both the user experience and security.
Why can it improve security?
- Users can focus on one strong password rather than maintaining many separate credentials
- MFA is enforced centrally instead of being configured separately for every application
- Access can be revoked centrally when a user leaves
- Centralized logs provide clear audit trails
- An unfamiliar fake login page can be easier for users to recognize during phishing attempts
Platformlar
Microsoft Entra ID (formerly Azure AD), Okta, Google Workspace IdP and Keycloak are common enterprise choices. Begin by identifying which applications support SAML or OIDC.
Riskler
SSO creates a central authentication point. If the identity provider is compromised, many systems may be exposed. Pair SSO with MFA, conditional access and strong monitoring.
