Remove Digital Signatures in PowerPoint 2013 for Windows

When your PowerPoint presentation is digitally signed and shared, it helps to validate your identity. At times, you may want to remove a digital signature attached to your PowerPoint presentation. Why? Maybe you want it signed by someone else, you may want to use another signature, or maybe there's no need for a particular presentation to be signed anymore. Follow these steps to remove the digital signature from a PowerPoint presentation in PowerPoint 2013:

1. Open the presentation that is digitally signed. Note that the open presentation will contain a yellow strip in the area below the Ribbon and above the Slide Area, as shown in Figure 1. The yellow strip indicates that this presentation is attributed read-only to discourage modifications. Note that the text message in the yellow strip reads Marked as Final; this is the same as the Mark as Final option we explored in a previous tutorial.

2. Click the Edit Anyway button (highlighted in red within Figure 1, above) within the yellow strip. This brings up the Microsoft PowerPoint window, as shown in Figure 2. Within this window, click the Yes button to remove the signature in this presentation and to enable editing.

5. Within the Signatures task pane, place the cursor over the signature you want to remove to get a downward pointing arrow next to the signature name, as shown in Figure 6, below. Click the downward arrow to bring up a drop-down list. From this drop-down list, select the Remove Signature option (highlighted in red within Figure 6).
