Definition
SSO lets a user sign in once and gain access to multiple applications. Authentication is centralised at an Identity Provider (IdP) such as Microsoft Entra ID (formerly Azure AD), Okta, OneLogin or Keycloak.
Security & Tech
Single Sign-On (SSO)
Single Sign-On (SSO) is an authentication method that lets users access multiple applications with a single login. Common standards are SAML 2.0, OpenID Connect (OIDC) and OAuth 2.0.
Key Standards
SAML 2.0 (common in enterprise), OpenID Connect (modern OAuth 2.0-based), Active Directory Federation Services (legacy Microsoft). teamly supports SAML 2.0 and OIDC.
SSO and Frontline Workers
For most frontline workers SSO is impractical because they have no corporate identity account. teamly provides phone-number login, employee-number with PIN and QR-code onboarding as alternatives, with SSO available in parallel for office staff.
