3 levels of signature

Level 1: Standard electronic signature (SES).

This is the simplest form: a scanned image of a handwritten signature placed in the document, or a signature "scribbled" with the mouse or tablet pen. Sign offers signing via scribbling or accepting.

3 levels of signature

Level 2: Advanced electronic signature (AES).

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

Sign offers the following options at this level:
- SMS: An SMS is sent to the addressee's cell phone with a code that he/she must enter on the signature page to get the document signed.
- Itsme: You can sign a document with an "Advanced" signature level.

3 levels of signature

Level 3: Qualified electronic signature (QES).

A qualified electronic signature works the same way as an AES, with one major difference: it uses a certificate issued by a Trusted Third Party. The signature is generated by trusted devices: governments that issue qualified certificates as national digital identities, or through commercial organizations. After the eIDAS amendment, a QES has the same legal validity as a handwritten signature.

Sign offers the following method:
-Itsme: The document is signed at a "Qualified" level.
