The Safari browser on your Mac can save certain types of data when you enter it. This includes things like usernames, passwords, credit card information, and more. This is helpful for filling out forms more quickly, as Safari can determine the type of field that is present on a Web page and fill in the appropriate information automatically.
But you might have many different types on information that you use, and Safari is autofilling fields with the wrong data. Fortunately you are able to turn off Autofill in the Safari browser on your Mac by following the steps in the tutorial below.
