How do I give SALARY access to my company's CCSS business eSpace on MyGuichet?

Granting Salary access to your company's CCSS business eSpace allows us to better assist you with error messages and declarations through SECUline. This article explains how to add Salary as a mandataire (representative) for your CCSS services.


Prerequisites


Before starting this process, ensure that:


  • You have a certified business eSpace on MyGuichet.lu
  • You have administrator access to your company's MyGuichet account
  • Your company is registered with the CCSS
  • Your company is using SECUline for CCSS declarations through Salary.lu


Adding Salary as a mandataire


To grant Salary access to your CCSS business eSpace:


  1. Log in to MyGuichet.lu with your authentication device
  2. Navigate to "My procedures"
  3. Click on "+ New procedure"
  4. Search for "CCSS : Request for professional space certification"
  5. Click on the procedure to start
  6. Complete the data protection consent by checking the required box
  7. Proceed through the next steps
  8. Fill in your contact information
  9. Proceed to Next step
  10. Enter your company's social security number and company name
  11. Proceed to Next step
  12. Under "Mandataire(s)" section, select:
  • "Yes" for "Do you have an authorised representative?"
  • "No" for "Is the authorised representative the same for each domain of activity?"
  1. Select only these three domains by checking the boxes for:
  • Employer data 
  • Affiliations 
  • Remunerations and work incapacities


Only these three domains must be selected to ensure Salary can provide support for your CCSS declarations and troubleshoot any issues effectively.


  1. For each selected domain, enter Salary's information:
  • Registration number: 2020220124699
  • Denomination: Salary S.A.
  1. Proceed to Next step
  2. Create a security code (6 to 10 characters) and enter it twice for confirmation


Remember your security code or store it securely. You will need to provide this code to Salary for them to complete the access setup. If you forget this code, you will need to redo the same procedure again to obtain a new access token.


  1. Click Next step to submit your request
  2. You will receive two separate letters from CCSS by postal mail within 72 hours:
  • First letter: Contains the security codes for each domain (these are for your records)
  • Second letter: Contains the mandataire access codes that have not yet been activated


The mandataire access codes will show as "Not activated" with an activation deadline of approximately 30 days from the request date.


  1. Once you receive the access codes, you must provide your security code to Salary:
  • Contact Salary support via email or through the online support chat
  • Provide the security code you created
  • Provide the mandataire access codes from the second letter
  • Confirm that you have completed the certification request


Salary will use your security code combined with the mandataire access codes to activate the access. The mandataire codes must be entered into the system before the activation deadline shown in the second letter, otherwise you will need to restart the entire procedure.


This access enhances our ability to support your SECUline integration by allowing us to identify and resolve issues more quickly, reducing delays in your CCSS declarations.


Salary only has consultation access to the selected domains. If you are using SECUline, we will continue to handle all your CCSS declarations automatically through the platform. You should not make declarations directly through MyGuichet as this would create conflicts with our SECUline submissions.
