Next, you’ll be prompted to enter some personal details consisting of your name, e-mail address, organization, and location. You don’t have to use every field here, but make sure to enter enough information so that the digital signature appears legitimate. Click Create when done.
Finally, you’ll be presented with the Sign option which will ask you to fill in the Purpose for signing this document. Once you’ve entered a reason, click Sign to complete the digital signature process.
The digital signature will remain valid until any modification is made to the PowerPoint presentation. If you do edit the presentation at a later date, you’ll need to sign the document again. However, you won’t be asked to repeat the entire process here. Since the digital ID that you just created will be stored, you’ll only have to perform the last step in the above process to sign the document again.
