For some surveys, the username and password combination are not secure enough and this method cannot be used. OneGate recognizes Electronic Certificates from Globalsign, Isabel and Quo Vadis. These are the same certificates that are accepted by E-Government-applications such as Finprof, Dimona, DMFA and DRS.

These certificates can be purchased from the following providers:

• Globalsign

Currently accepted certificates:

✓ GlobalSign GCC R45 PersonalSign 3 CA 2020

✓ GlobalSign GCC R45 PersonalSign 3 CA 2022

• Isabel

Currently accepted certificates:

✓ Isabel Certification Authority

✓ Isabel Certification Authority Root

• Quo Vadis

Currently accepted certificates:

✓ QuoVadis Belgium Issuing CA G2

✓ QuoVadis EU Issuing Certification Authority G4

These providers issue Electronic Certificates after payment and after authentication by the applicant. It is therefore necessary to retrieve these certificates in person with an ID-card.

When logging in to OneGate, choose the option "identification with an Electronic Certificate" and choose a copy of the certificate.
During the first login, the declarer will be asked an additional identification. The declarer will thus have to enter an identification-code (KBO-number). During the next hours, access will be granted to the user. This is confirmed via email.
If the certificate was already registered and valid, the user will get immediate access.

If you use the same certificate for another Bank application (BECRIS, Supervision, CAP2), you can use the same information (NUIN starting with 0002/3/5/7-) to connect to OneGate.

Since 2022, it is possible to connect securely to OneGate through the "CSAM" portal dedicated to Belgian general interest services. This system is already used by other federal applications such as Intervat, Finprof, Dimona, DMFA, ...

In addition to guaranteeing your identity at the level of access to the OneGate application, you can now manage your own accesses and the accesses of your employees thanks to the federal service My eGov role management.

A page on our website is dedicated to this type of connection. Additional information can be found directly on the CSAM portal site.

If the OneGate Admin role cannot be found at step 3 'Role selection' on the My eGov role management website, make sure you have access to the economy domain on the social security's website.

If you would like to use CSAM to access the OneGate test environment and your company was not set up in the Belgian Social Security test environment, you will first need to send an e-mail requesting the creation of your company.

Upon receiving confirmation that your company has been created, please follow the steps below:

1. Activate your digital keys (first connection with eID card reader!)
2. Assign the OneGate Admin
3. Create users in OneGate based on their National Number: https://a-onegate.nbb.be

The OneGate-Application allows declarers to give access to a third party, such as an(accounting firm, a tax representative or a person in charge of a VAT-unit,  to fill in their surveys for them.

• If you logon with CSAM, you should use the OneGate’s User Management module (CSAM method) to create a third-party user.
• If you logon with an electronic certificate, you should complete this delegation form and send it to the OneGate Access Management Team. They will take all next steps regarding the Third-Party activation.
