This information is intended for developers and owners of services using BankID. As previously informed we will change content of the server certificate used to protect the BankID Service. This updated information is only to inform you that the change has been postponed to mid May 2020.

We will include SAN (Subject Alternative Name) in the server certificate used to protect the BankID Service. This change should not have any impact on your service, the SAN is a standard extension and has been used to protect web sites for many years. The change has already been done in the test environment.

Note: This information is also a reminder of our recommendation to only add the CA certificate as trusted in your service. If you also added the server certificate, your service will fail when we replace the server certificate.

The following summarizes the changes:

  • We will include SAN in the server certificate protecting
  • The server certificate is planned to be replaced in mid May 2020.
  • The CA certificate that issues the server certificate is not changed.
  • The change has already been done (since January 2020) in the test environment
  • We regularly change the server certificate. We remind you to not explicitly trust or pin the server certificate. Only the CA certificate should be explicitly trusted.
