Signing with a Qualified Electronic Signature (QES)

Other Verification StepsRevision: 2026-06-26Language: EN

A Qualified Electronic Signature (QES) gives your digital signature the same legal weight as a handwritten one — learn how to sign.

A Qualified Electronic Signature (QES) is the highest level of electronic signature defined under EU regulations (eIDAS). It carries the same legal effect as a handwritten signature and is legally binding across EU member states. Some businesses require a QES when signing contracts, consent forms, or regulated agreements during onboarding.

Why a QES is requested

A business may request a QES when the document being signed has regulatory or legal significance — for example, an account opening agreement, a financial services contract, or a consent form under applicable law. The QES step is always configured by the business and will be shown to you only when it is required.

How to complete the QES step

Review the document presented to you carefully before signing.

Follow the on-screen instructions provided by the qualified signing service — this typically involves a secure confirmation step that binds your signature to your verified identity.

Once you confirm, your signature is cryptographically bound to the document.

You will receive a copy of the signed document for your records, if the business provides it.

The QES process relies on the identity data already captured earlier in the verification flow to bind the signature to a verified identity. If you have not yet completed the identity verification steps, you will be prompted to do so before the signing step can proceed.
