Procedure to access the Filing application

To access the CBSO Filing application, a modern external interface is used, CSAM, the portal for online government services.

Various types of digital keys can be used to log in.

Logging in with an electronic ID card

	You can use your identity card and an eID card reader to log in. This is the standard procedure to access various Belgian government online services and guarantees the highest level of protection. To log in with your eID, you will need the following:
	Your eID card. Always insert your eID in the card reader before going to the online portal.
	A four-digit PIN.
	Appropriate software to use your eID. This can be downloaded for free at Download eID software (belgium.be).
	A card reader:: Built-in card reader: Some computers and keyboards have a built-in card reader. Stand-alone card reader: You can easily connect a stand-alone card reader to your PC with a cable.

If you have questions about how to use your eID, please visit the CSAM Help Centre (eID card reader).

Logging in with itsme, your digital ID

You can use your digital ID to log in securely with your smartphone.

In order to use this option, you must first register with itsme.

You can find more information about itsme and how to register in this brochure and at itsme®-app | Ontdek itsme®

If you have questions about itsme, please visit the CSAM Help Centre (itsme®).

Logging in with an EU-recognised login tool via eIDAS

Citizens of other European Union countries can use eIDAS to log into Belgian government online services with their national means of identification and authentication.

A list of countries for which a national identifier can be used to log in can be consulted by choosing “Log in with an EU-recognised login method” when logging in to an online service.

More information can be found on this web page.

For questions about eIDAS, please visit the CSAM Help Centre (eIDAS).

Logging in by other means

For foreign nationals who cannot use an eID, itsme or eIDAS to log in, access by means of an electronic certificate will be possible until 24 December 2023. For a permanent solution, we are awaiting the development of an online authentication registration office (a virtual counter) and the subsequent distribution of digital keys.

Only the following electronic certificates may be used:

GlobalSign- PersonalSign 3 Pro Certificate
Quo Vadis EU qualified certificates Quo Vadis BE qualified certificates
Isabel 6

A list of supported Certificate Authorities (CA) can be found here.

When prompted, select the certificate you wish to use.

Enter your PIN code.
