How to add password or OTP protection


SigningHub employs various authentication options, in some situations users can add an additional layer of access security to their documents.

SigningHub allows users to electronically sign documents. An Electronic signature is not linked to the Signer’s real-life identity, however, SigningHub will ‘Witness’ sign the document with a timestamp to protect the integrity of the document.

During the electronic signing workflow, SigningHub will send an email with a link to the document to the Signer. To make the signing process as easy as possible, clicking on the link will open the document in SigningHub immediately without requesting the user to authenticate. These types of signing workflows are ideal for documents that do not require high trust like memos, school letters, leave applications, attendance registers, visitor forms, approvals, expense claims, etc.

To protect the confidentiality of the documents, SigningHub provides document owners with the option of adding either a password or a One-Time-Pin sent to the Signers mobile phone.
