GDPR-compliant password sharing in Belgium

Belgium's data protection authority — the Gegevensbeschermingsautoriteit (GBA) — is known for its active enforcement posture. Belgian organizations, particularly in financial services, healthcare, and the public sector, face meaningful compliance pressure. When it comes to credential sharing, many organizations have not yet applied the same scrutiny they give to customer data handling.

This article examines the GDPR obligations most relevant to password sharing in the Belgian context and what organizations can do to satisfy them.

The GBA's enforcement approach

The GBA has issued significant fines across various sectors and has been willing to investigate complaints relating to inadequate technical security measures. Under Article 32 of the GDPR, organizations must implement "appropriate technical and organisational measures" — and "appropriate" is evaluated in the context of the risk involved.

Credentials granting access to systems containing personal data are high-risk assets. How they are shared is therefore squarely within the scope of Article 32 assessment.

Key GDPR principles and their application to credential sharing

Article 5 — Principles relating to processing

Integrity and confidentiality: Credentials must be protected using appropriate security. Sending passwords in plain text emails fails this standard. Encrypted, one-time delivery links satisfy it.

Storage limitation: Personal data — including access credentials — should not be retained beyond what is necessary. Email threads containing credentials have no deletion mechanism. Self-expiring links are deleted automatically.

Data minimization: Only share credentials with those who need them. One-time links prevent inadvertent forwarding from creating additional unauthorized access points.

Article 32 — Security of processing

Organizations must consider the risks associated with accidental or unlawful access. An assessment of credential sharing practices should ask:

• Could a shared password be intercepted in transit?
• Is there a persistent record of the credential in an uncontrolled location (email, chat)?
• Is there a mechanism to revoke access if the credential is shared incorrectly?

A one-time link with encryption and automatic expiry directly addresses all three questions.

Article 28 — Processor relationships

If you use a third-party tool to share credentials, that tool is a data processor. You must have a written Data Processing Agreement (DPA / verwerkersovereenkomst) in place. Verify that your chosen credential-sharing tool offers this.

Article 30 — Records of processing activities

Organizations with more than 250 employees (and some smaller ones in high-risk sectors) must maintain records of their processing activities. Credential sharing via a documented, controlled tool is easier to describe and justify in an Article 30 record than ad hoc email sharing.

Belgian-specific considerations

Sectoral regulators: Belgian financial institutions are supervised by the FSMA and NBB, both of which have issued guidance on information security that goes beyond GDPR. Healthcare organizations face additional requirements under Belgian law. In both cases, strong technical controls around credential sharing are an explicit expectation.

Cross-border operations: Many Belgian organizations process data across the EU or work with processors in other member states. Using an EU-based credential-sharing tool simplifies the data transfer compliance picture. Organizations that also operate across the border can consult our guide to GDPR-compliant password sharing in the Netherlands.

Bilingual environments: Organizations operating in both French and Dutch need tools that work for all staff. A tool with a clear, simple interface in multiple languages reduces friction and increases adoption.

Practical compliance checklist for Belgian organizations

• [ ] Prohibit credential sharing via email, Teams, or WhatsApp by policy
• [ ] Adopt a dedicated credential-sharing tool with EU data residency
• [ ] Sign a DPA with the tool provider
• [ ] Ensure credentials are deleted after retrieval and/or after a defined expiry period
• [ ] Add the tool to your Article 30 records of processing activities
• [ ] Train staff on the new process and the reasons for it

The bottom line

GDPR compliance for password sharing does not require a complex technical implementation. It requires replacing an insecure habit with a secure one — and using a tool that is designed for the purpose. For Belgian organizations under GBA scrutiny, demonstrating that you have taken this step is a meaningful part of your overall compliance posture.
