CO2-registry: switching from GSM/SMS to QR-code

Until today, the most registry users use a method based on GSM/SMS for authentication and transaction signing by receiving SMS containing a temporary unique challenge code. In order to improve the reliability of the authentication the European Commission has chosen for an EU Login mobile app to enable users to connect to EUCR application. This method shows to be more secure and reliable than the SMS/GSM method.

The new authentication method is already available in a transition phase, which means the users are still able to use the old GSM/SMS method. Once the transition period is over (September 2021) all the users must use the soft token as a second factor of authentication (password is the first level of authentication).


The EU Login mobile app is free and can be obtained from the Google Play Store (Android) and the App Store (iOS). The current list of devices/mobile operating systems which should run the app with higher confidence (so called 'whitelist') is available here. If you have Huawei mobile devices, please read carefully the specific note.

Important: please be sure you have switched from GSM/SMS authentication method to a QR-code method as soon as possible. You may find the instructions to use the new authentication method in the Manual to create EU Login account and URID. After September 2021 it will be not (not be) possible to login into CO2-registry with the old GSM/SMS method.

Once the user logs in using the EU Login mobile app, he or she will not be able to use the GSM/SMS verification method anymore.
