As a developer, you may want to disable this feature for some types of input including credit card information. ASP.NET has the ability to override the user's choice with the autocomplete attribute by setting it to off. This can be added to a form tag or an individual TextBox control.
<form runat="server" autocomplete="off"></form>
<asp:TextBox ID="tbCreditCardNumber" runat="server" autocomplete="off" />
tbCreditCardNumber.Attributes.Add( "autocomplete", "off" );
Alternatively, you can use the AutoCompleteType attribute on an individual TextBox control and set it to Disabled to achieve the same result.
<asp:TextBox ID="tbCreditCardNumber" runat="server" AutoCompleteType="Disabled" />
tbCreditCardNumber.AutoCompleteType = AutoCompleteType.Disabled;
