What is the difference between electronic signature and digital signature?

Electronic signature and digital signature are synonyms that reflect the three categories of electronic signature defined by Law 14,063/2020. They are: simple electronic signature (which offers the simplest form of authenticating the signer), advanced (authenticated by tokens, selfie, Pix, and other means of verifying the authorship and integrity of electronic documents) and qualified (which uses a Digital Certificate accredited by ICP-Brazil).

What is an electronic signature?

The electronic signature has the same purpose and the same dynamics as a physical signature. It is yet another way, but electronically, to identify a person, authenticate them and link them to a document, ensuring that it has not been modified later. The advantage of an electronic signature is that it is more convenient, faster, and even more secure than a physical signature
