The Safari browser in iOS, iPadOS, and macOS can automatically retain information entered in fields on websites you visit and then automatically complete it on your next visit. This can be great! You don’t have to re-enter the same information, like an account name or email address.
However, it’s tedious when you don’t want the same information re-entered each time. There’s a simple way to disable this, but since it’s not available on a site-by-site basis, it’s a nuclear option. You can disable it always or not at all. (AutoFill is typically used to mean filling forms by selecting a profile or items from a list; autocomplete usually results from starting to type into a field, and having previously entered matches appear among which you can select.)
