Bug 1587214 (e.g. https://github.com/web-platform-tests/wpt/pull/19579) adds support for running WebAuthn web platform tests with a VirtualDriver-compatible test authenticator. Gecko's soft token needs to be adapted to implement that VirtualDriver mechanism.

This will be esstentially a rewrite of the soft token's interface, requiring it to be exposed far more than it currently is.

The work for this should basically advance Bug 1529973, or we run the risk that what we do here drives that ball backward.

WebAuthn WPTs are being disabled in Bug 1634715, and this bug will need to re-enable them as it enables the VirtualDriver.

I badly want bug 1536482. Is there something I can do to help out with this? If you can mentor me, I can probably pitch in.

What's the status here? I'm trying to figure out what we need to do to make sure we get wpt coverage for those APIs that have additional WebDriver endpoints. Is this work blocked on something specific? Is there help needed from the automation side to make progress?

Mmm, I have some duplication going here, I guess I forgot this one when I was filing Bug 1676679.

Let's let that one, with its more detailed info, describe the technical tasks and let this one be the enablement of the relevant WPTs.
