The use cases for logging in and out must be implemented in the testing or development environment of the e-service. Because Suomi.fi e-Identification contains a single sign-on functionality, each e-service connected to it must also support single logout. What this means in practice is that the e-service must support six use cases in relation to identification:

  • sending an identification request
  • receiving an identification response
  • sending a logout request
  • receiving a logout request
  • receiving a logout response
  • sending a logout response.

Implement and test all use cases before production roll-out.
