Digitally signing a Word document is an important way to protect the integrity of the document and ensure the authenticity of its contents. By digitally signing a Microsoft Word document, the author or company acknowledges that they are responsible for the content and terms stated in the document and stands behind the document’s accuracy and validity. This type of digital signature gives recipients assurance that the document has not been altered in any way since it was signed by its creator. Digital signatures also give legal validity to documents, as they show proof of intent, authorization, and acceptance.
