The public key of your ADE certificate, which you need for automatic device registration of Apple devices, is valid for five years. It is usually renewed automatically. However, the associated token becomes invalid as a result of this renewal.
Aim
In this how-to guide, we will show you how to renew the token for your ADE certificate if it has become invalid due to the public key being updated.
Implementation
Note! Occasionally, the ADE certificate (public key) may not renew automatically. In this case, click “Renew” before continuing as described below.
Once your ADE certificate (public key) has been renewed (or renewed by you), the token associated with the certificate loses its validity (left arrow in the image, No token available) and must be updated in Apple Business Manager.
- To do this, download the new ADE certificate (public key) (right arrow in the image).

- Then open Apple Business Manager and log in with your credentials.Click on your profile in the bottom left corner of the menu (lower arrow in the image) and then on Settings (upper arrow in the image).

- Now select your device management service (left arrow in the image) and then click Edit (right arrow in the image).

- Then, under Service Settings→ Upload Public Key, click Replace Certificate (arrow in the image).

- Now upload the ADE certificate with the public key that you downloaded in the last step in the Cortado administration portal.
- Then click on Save (arrow in the image).

- Now you can download the new token by clicking on Download Token (arrow in the image).

- Select the profile with the invalid token in the Cortado administration portal (left arrow in the image) and then click Edit (right arrow in the image).

- Upload the new token to your ADE profile (upper arrow in the image) and then click OK (lower arrow in the image).

The token is now valid for another year. We show you how to renew the token after this period in our How-To guide.
