Disabling browser autofill in a form

Today I learned that autocomplete="off" tends to be completely ignored by browsers these days because they seem to have the attitude that websites don’t use it correctly.

Apparently the best way to prevent a browser from trying to autofill a field is to tell the browser it’s not the field it thinks it is with something like autocomplete="something-else". If it’s anything the browser doesn’t recognize it won’t try to fill it. It looks like autocomplete="new-password" is one people tend to use especially for any type="password" fields that aren’t actually meant to be a user’s login password. See this StackOverflow question for more discussion.

Likewise if you want to give the browser hints about what it should​​​​​​​ try to suggest you can use one of the recognized values like address-line1.
