Single sign-on (SSO) is an authentication method in which a user signs in once with a central identity provider (IDP) and can then access all authorized services without having to sign in again.
How it works
- The user signs in with the identity provider (e.g. company Active Directory via LDAP)
- The IDP issues a token
- With this token, the user can access all connected services (including the appointment scheduling system)
Advantages
- One single, secure password instead of many weak passwords
- Reduced phishing risk
- Central user and permission management
Disadvantages
- Dependence on the identity provider (if it fails, access to all services is blocked)
