In addition to that convenience, document signatures can provide peace of mind, helping you add professional polish and security to Word, Excel, and PowerPoint documents.
Why Use Signatures in Microsoft Office Documents?
But does this really matter? According to Microsoft’s help site, these signatures offer authentication, ensuring that:
The digital signature is valid.The certificate associated with the digital signature is current (not expired).The signing person or organization, known as the publisher, is trusted.The certificate associated with the digital signature is issued to the signing publisher by a reputable certificate authority (CA).
In this way, a document’s digital signature helps preserve the integrity of your document, both for yourself and those you share documents with. So, while you probably don’t need to sign every document you create in Microsoft Office, you can benefit from adding signatures to certain documents.
