Kind of, but to be fair UAC doesn’t prompt you for the account password unless you’re not an Administrator on the PC (in which case you have to enter the password of someone who is). If you’re on a single user PC, you’ll be an admin and it’ll only be a “Yes / No” prompt.
Now macOS on the other hand does require the password, unless you have an Apple Watch (if I heard correctly) in which you can confirm it by pressing a button on it. Or, using the fingerprint reader on the Macs with a TouchID sensor.
