The main problem with disabling HTML form input autocomplete autofill is that it can make it difficult for users to complete forms. This can be especially problematic on websites where forms are used to collect data from users. If users are unable to complete forms, this can lead to lost data and potentially lost business.
<input type="text" autocomplete="off">
The code line above creates an input element of type text, with the autocomplete attribute set to “off”. This disables the browser’s autocomplete feature for this particular text input field.
Browser autocomplete and autofill
Browser autocomplete and autofill are features that allow users to type in a word or phrase and have the browser automatically fill in the correct web address or other information. This can be helpful when you’re trying to find a particular website or piece of information on the web.
