How sign works

4 simple steps

Easily sign documents electronically with our streamlined process:


Three levels of signature

To sign a document digitally, Sign offers all three levels of signature as defined by the eIDAS Regulation. The sender determines the level of signature required for each document.

Level 1
Simple instead of standard (SES)

The SES is used for everyday documents: an accept button or a signature ‘scribbled’ using the mouse of tablet pen. Sign offers a signing via scribble, accept or a read confirmation.

Level 2
Advanced Electronic Signature (AES)

An advanced electronic signature will link the identity of the signer to the signature, via an unique code, which is derived from the message itself and the identity of the sender. These signatures are much more reliable than a SES.

Sign offers the following options at this level:

a SMS is sent to the mobile phone of the addressee with a code that he/she has to enter on the signing page to get the document signed.

You can sign a document with an ‘Advanced’ sign level.

Level 3
Qualified Electronic Signature (QES)

A qualified electronic signature works in the same way as an AES, with one big difference: it uses a certificate issued by a Trusted Third Party. The signature is generated by trusted devices: governments issuing qualified certificates as a national digital identity, or via commercial organisations. Following the eIDAS amendment, a QES has the same legal validity as a handwritten signature.

Sign offers the following method:
