Login creation not smooth at disneyplus

My pleasure.

I have a subscription to 1Password but I get the Mac version and updates from 1Password directly, not from the app store.

I do have reservations about trying that out.

Would installing this from the app store have any implication for the future? I don't want to get locked into having to use the Mac app store for 1Password if I can help it. I do have one app that I have to get from the store, probably because I subscribed to its iOS version first and there may have been no other option available, but otherwise I install/check for updates/update everything directly from vendor sites.

Also, when done with the test, beyond turning off this new extension, is there a way to completely and cleanly remove it? For instance, on my system (Big Sur) I have

~/Library/Containers/com.apple.Safari/Data/Library/Safari/AppExtensions/Extensions.plist

which has entries for all my currently installed extensions.

I presume this extension would be its own, separate app - but do you also create separate data folders everywhere in ~/Library? Or would this extension be using the same folders the original extension uses, so that they would get kind of entangled? Maybe using separate files, but in the same folders. I've seen your instructions in https://support.1password.com/uninstall-1password/ but that isn't describing what I'd want to do.

That's a lot of questions, and you probably didn't sign up for giving me a tutorial about Mac app extension management, so probably the easiest thing for you to do is conclude I may not be the best guy to help you out with this kind of thing :).
