How to Add a Digital Signature in an MS Word Document

Digitally sign your Microsoft Word documents with this easy-to-use guide

Last Updated: August 23, 2022 References Tested

A digital signature can refer to two different things—using a simple electronic version of your regular hand-written signature, or using a digital signing certificate to add an encrypted stamp of authentication to a document. If you need to add your handwritten signature to a Microsoft Word document, we'll show you the easiest ways to do so in Windows and macOS. We'll also show you how to use your digital ID (issued by a certificate authority) to digitally sign a Word document in Windows.

Method 1

Method 1 of 4:

Using DocuSign (Windows and Mac)

Using a Digital Certificate (Windows)

1
Create a digital certificate if you don't already have one. Signing with a digital signature is different than typing or signing your name on a document. When you sign with a digital certificate, you're including a unique encryption code that validates your identity. Digital certificates are usually assigned by certificate authorities and cost money, but you can create one yourself for personal use.^{[2]

Community Q&A

Question

When I try to save a copy of a digitally signed Word 2007 document, it invalidates the signature. Is there a way of saving without invalidating the signature?

Community Answer

You need to save the document first, and then sign digitally. There is no need to save it again.
Question

Our forms have sections with a signature required in each section. But when you complete the next section, it invalidates the signature for the previous section. Is there a way around that?

Community Answer

Then it's some digital signature issue. You may need to seek technical assistance for that.
