Password Autofill extensions on MacOS Big Sur?

I noticed that when searching for "Password" in System Preferences, the option "Passowrd AutoFill Extensions" pops up, but there is not corresponding item for it in the section.

Is there any info on this framework and how it can be used by password manager apps? Is there an example of an app that uses this? Thanks in advance!



It's part of the Authentication Services. It's been around on iOS since 12, but it is new to the Mac on macOS BS.
