One shot on-demand certificates cannot be revoked because they are only valid for 10 minutes. You can revoke your organisation certificate in various ways.


If you wish to revoke a certificate due to compromise, invalidity or other reasons, you can start a revocation request here. Please note: The revocation cannot be revoked and the Signing Service will only be able to issue seals for your organization after a new application and installation of a follow-up certificate.

Only those persons who have been named as representatives of the organization in the certificate application and have been identified electronically with the RA-App are entitled to immediate revocation. The mobile phone number stored in the identification is required for the release of the revocation. Please be also prepared to enter your "ClaimedID" of your technical account with which your application addresses the All-in Signing Service.
