# What is an Autograph Signature?

A **Handwritten/Autograph Signature** is an **A**dvanced **E**lectronic **S**ignature (AES) for signing documents with a high level of legal and secure signature. Signers may sign on the screen using a pen or a finger or even using a mouse from a computer. All data is sealed and encrypted to prevent any modification and electronic signature is uniquely linked to the signer.
