The purpose of a digital signature is the same as your handwritten signature.  Compared to a handwritten signature, it is considered significantly more difficult to forge a digital signature. A valid digital signatures assures the recipient of your document that:

  • Authentication – you are the sender of your document
  • Integrity – the document has not been altered since you signed it
  • Non-repudation – you can’t deny the authenticity of the document

Digital Signatures are a great tool to keep your documents secure, and to keep your data electronic to avoid wasting paper.
Unfortunately, Office 2011 for Mac doesn’t include this feature; in order to electronically sign a document you must be using Word 2013.

To add a signature line to your document
1) Select the Insert Ribbon
2) In the Text section, select the Signature Line button

3) In the Signature Setup menu, select your desired options (Suggested signer, show dates, allow comments).

To sign a document
1) Double click the signature line in the document.
2) Either type your name or upload a picture of your signature.
Once a document has been signed, the Signature Icon Screen Shot 2014-12-19 at 1.10.40 PM (2) will be displayed in the bottom left.
Note: The document must be re-signed if any changes are made, so make sure you’re finished editing before you go to sign.
