Zefort Sign authentication levels

Zefort Sign offers two authentication levels: basic authentication with email or SMS and strong authentication with online bank login identification or some other nationally available authentication method. The strong authentication option may not be available in all countries.

You can select the authentication level when creating the signing request:

  • In basic authentication, the recipient of the signing request receives via email a link to a web page, where the signer can review and sign the document.
  • You can also use SMS authentication: in this case recipient will receive email link to the contract and SMS with the verification code.
  • In strong authentication, the signer receives the same web page link, but is also required to complete a strong identity verification process when signing the document.

Good to know – three levels of electronic signatures

The European Union eIDAS digital identification regulation defines three levels of electronic signatures: basic, advanced, and qualified electronic signatures.

Zefort’s basic authentication corresponds to the basic level defined in eIDAS. At a basic level, the name written in an email can be called an electronic signature, for example. However, in the basic level, it is not possible to link the signature indisputably to an individual person.

Zefort’s strong authentication corresponds to the advanced level defined in eIDAS. In this case, it is possible to uniquely link the electronic signature to the signatory.

The qualified signature level defined by eIDAS requires that the signatory uses a dedicated qualified signature creation device (QSCD) when signing the document. Zefort does not currently support qualified electronic signatures.
