The OED's role is to check the future bearer's identity during a face-to-face, to whom we wish to give a qualified signature certificate (level3).
Going onto the "Identity" tab on https://app.universign.com, it is possible for someone having the Universign's prior authorization and a physical person certificate to obtain the OED status, passing a training.
1) The first step introduces the OED's role and invites to download a training PDF.
2) The second step is a quizz allowing to validate the acquired knowledges after reading the PDF.
You can try to answer several times if you failed or didn't understand some elements.
3) The third and final step is the mandate signature of OED.
After signing the mandate, the OED's role is active without any delay.
The training is also available from this link if you already have a certificated identity:
