Password type input with autocomplete enabled
The autocomplete attribute works with the following <input> types: text, search, url, tel, email, password, datepickers, range, and color.
The autocomplete attribute specifies whether or not an input field should have autocomplete enabled.
Autocomplete allows the browser to predict the value. When a user starts to type in a field, the browser should display options to fill in the field, based on earlier typed values.
<form action="demo_form.asp" autocomplete="on"> First name:<input type="text" name="fname"><br> Last name: <input type="text" name="lname"><br> E-mail: <input type="email" name="email" autocomplete="off"><br> <input type="submit"> </form>
