eIDAS Regulation: Simple and Complete Explanation

eIDAS in One Sentence

eIDAS (Electronic IDentification, Authentication and trust Services) is the European regulation No. 910/2014 that unifies the legal framework for electronic signature, digital identity, and trust services in the 27 Member States.

It entered into application on July 1, 2016 with direct force of law in each Member State.

Why eIDAS Was Created

Before 2016, each country had its own law. A signature issued in France was not automatically recognized in Germany.

eIDAS solves three problems:

• Legal fragmentation: a single framework for 27 countries

• Mutual recognition: a signature valid everywhere

• Harmonized levels: three standardized levels (SES, AES, QES)

The Three Signature Levels

• Simple signature (SES): any electronic consent

• Advanced signature (AES): unique identification + strong authentication

• Qualified signature (QES): AES + qualified certificate + secure device

For details, see simple, advanced, qualified.

Trust Service Providers (TSP/QTSP)

eIDAS creates the status of trust service provider (TSP), which can be qualified (QTSP) if it is audited and registered on the trust list of a Member State. In France, the ANSSI maintains this list (Docaposte Certigna, Universign, CertEurope…).

Mutual Recognition

A signature issued by a French QTSP is automatically recognized throughout the EU. This principle also applies to digital identities: FranceConnect+ will be interoperable with identity wallets from other States under eIDAS 2.0.

Non-Discrimination Principle (Article 25)

Even a simple signature is admissible. The judge assesses the reliability of the process, but the digital format alone is not grounds for rejection.

eIDAS 2.0: What Changes

Regulation (EU) 2024/1183 modernizes eIDAS with the European Digital Identity Wallet (EUDIW). By the end of 2026, each State must offer a mobile application to store identity credentials and sign with a QES.

What It Changes for Your Business

• Sign with EU counterparties without negotiating the framework

• Choose an eIDAS-compliant provider

• Prepare for EUDIW (2026-2027)

• Adapt the level to the stakes

FAQ

Is eIDAS mandatory?

Strongly recommended for any signature with cross-border EU legal value.

Difference between eIDAS and GDPR?

eIDAS governs signatures and identities. GDPR governs data protection. Complementary.

Can I sign with a non-EU provider?

Legally yes, but cross-border recognition is lower.

Does ANSSI certify platforms?

ANSSI qualifies QTSPs (for QES). For SES/AES, it is the provider's eIDAS compliance.

How do I know if a document is signed in QES?

In Adobe Reader: signature properties → level and certificate. See verify a signed document.

Conclusion

eIDAS is the European foundation that makes electronic signature legally reliable, cross-border, and standardized.
