Authentication
Definition
Authentication is the process of verifying the identity of a user or system before granting them access to a service or authorizing the application of an electronic signature. It can be simple (password alone), strong (multi-factor) or biometric. The robustness of authentication directly determines the signature level achievable: an AES requires at least two distinct factors.
Frequently asked questions
What is authentication in the context of an electronic signature?
It is the process that verifies a user's identity before allowing them to apply an electronic signature.
What levels of authentication exist?
Authentication can be simple (password only), strong (multi-factor), or biometric.
Does the authentication level affect the achievable signature level?
Yes — the strength of authentication directly determines the signature level that can be reached.
How many authentication factors does an advanced electronic signature (AES) require at minimum?
At least two distinct factors, which corresponds to strong authentication.
