macOS Catalina's Preview App Lets You Sign Documents on Mac Using iPhone or iPad

In macOS Catalina, the Preview app has a new feature that makes it easier to sign PDFs and other documents by leveraging an iPhone or an iPad running the iOS 13/iPadOS operating system.

Rather than using the Trackpad to create a signature, or scanning a piece of paper, you can connect to your ‌iPhone‌ or ‌iPad‌ to sign there using either a finger or an Apple Pencil.

In the Preview app, under Tools > Annotate > Signature > Manage Signatures > Create Signatures, there is a new option to choose to create a signature with an iOS device. Clicking on this option lets you select an available ‌iPhone‌ or ‌iPad‌ to use.

Devices running iOS 12 will show up in this list, but creating a signature only works on a device running iOS 13. Selecting an ‌iPhone‌ or ‌iPad‌ with iOS 13 will pop up a simple signature interface on the device in question, where you can sign with a finger on the ‌iPhone‌ or a finger or ‌Apple Pencil‌ on ‌iPad‌.

After you've signed, tap the done button, and your signature is instantly made available in the Preview app as an option to be inserted into your documents.

We needed to have the devices unlocked to get the signature interface to pop up, but this may be a bug that will be addressed in a later beta.

You can already sign PDFs right on the ‌iPhone‌ or ‌iPad‌ using Markup features, but the new Preview option is a useful, streamlined way to get a signature on a document if you start the process using a Mac.

I still don’t understand why Apple is so afraid of touchscreens on Macs when they are so good with them on mobile devices. It’s so much easier just to sign on the screen. Goofy workarounds like this should be unnecessary for the prices Apple charges.
I can list many reasons why Apple shouldn't put touchscreens on Macs but you probably already heard them before and disagreed.

Apple is blurring the lines between iOS and Mac in terms of functionality and cross-utility. It’s a brilliant strategy to leverage their success with iOS and encourage even more people into the Mac fold. Looking back I think the recent plateauing of iPhone sales is probably the best thing that could’ve happened to Apple users - it’s forced Apple to reevaluate their entire product line and look for ways to improve synergy and platform lock-in to increase company-wide revenue.

That is all well and good.
But this analog signing method is just last century.

Opinion;:
macOS under the Preview app. should support signing using digital signatures, even if one does not own a certified public-key/private-key pair (thus, signing with self as the certificate authority).

The image of the iPhone has an interface that says: "sign your name using your finger or pencil."; is that a real screenshot? a doctored image? If it's a screenshot, is it a mistake in iOS 13 or a sign that pencil support for (maybe the next) iPhone is finally coming with iOS 13?
