What is eIDAS?

eIDAS (Electronic Identification, Authentication, and Trust Services) is an EU regulation that provides a standardized legal framework for electronic identification and trust services across all EU member states. It defines how individuals, businesses, and public organizations can securely sign, share, and validate electronic documents with full legal recognition throughout the European Union.

Why was eIDAS introduced?

Before eIDAS, each EU country had its own rules governing electronic signatures and digital transactions, making cross-border recognition difficult. The regulation was introduced to create a single digital trust framework, ensuring that an electronic signature made in one EU country is legally valid in another. Its goal is to strengthen security, transparency, and trust in digital interactions while enabling seamless cross-border business and public services.

How does eIDAS support digital business across borders?

eIDAS defines three levels of electronic signatures based on their security and verification strength:

  • Simple Electronic Signature (SES) – The most basic form, used to show intent to sign (e.g., typing a name or clicking “I agree”).
  • Advanced Electronic Signature (AES) – A more secure type that is uniquely linked to the signer and capable of detecting any document tampering.
  • Qualified Electronic Signature (QES) – The highest level, created with a qualified digital certificate issued by a Qualified Trust Service Provider (QTSP). QES offers the strongest legal standing and is recognized as equivalent to a handwritten signature within the EU.

How does eIDAS support digital business across borders?

eIDAS enables businesses, individuals, and public authorities across the EU to recognize and trust each other’s electronic signatures and digital identities.
By establishing mutual recognition among member states, it removes the legal and technical barriers to cross-border digital transactions. This allows contracts, financial documents, and regulatory filings signed in one EU country to be legally valid in another—simplifying international operations, improving compliance, and fostering a secure digital single market.
