Some 3rd party security applications will flag the built in AutoComplete SharePoint functionality as a security risk when users access the SharePoint resources on a public machine.

Recommendations include setting autocomplete to "off" on all your forms. 

Or, writing some custom code to override the feature.

 

Here is some SAMPLE CODE that can be used in conjunction with a client created custom.js to override the Autocomplete feature in SharePoint:

 

1.     Create feature files that will inject content into the master page "AdditionalPageHead" section.

 

2.     Create a new feature folder under SharePoint. Add the Feature.xml and CustomSchema.xml files like below:

 

 

TEMPLATE\FEATURES\DelegateControl\feature.xml

Feature.xml
===================
<?xml version="1.0" encoding="utf-8"?>
<Feature Id="<GUID>"
Title = "AUTOCOMPLETE Disable"
Description = "AUTOCOMPLETE Disable"
Creator = "creatorName"
Version = "1.0.0.0"
DefaultResourceFile=" "
Hidden ="TRUE"
Scope="WebApplication"
xmlns="http://schemas.microsoft.com/sharepoint/">
  <ElementManifests>
    <ElementManifest Location="CustomSchema.xml" />
  </ElementManifests>
</Feature>



CustomSchema.xml
=====================
<Elements xmlns="http://schemas.microsoft.com/sharepoint/">
  <Control Id="AdditionalPageHead"
  Sequence="80"
  ControlSrc="~/_controltemplates/custom/custom.ascx">
  </Control>
</Elements>

2. Create a custom.ascx file and place it in the TEMPLATE\CONTROLTEMPLATES\custom\ directory of the 12 hive

Custom.ascx
====================
<%@ Control Language="C#" %>
<script type="text/javascript"
src="/_layouts/Custom/Custom.js" defer="true"></script>

3. Create your custom.js and place it in the Layouts/Custom/ directory of the 12 hive

Custom.js
====================
if (document.getElementsByTagName) {
  var forms = document.getElementsByTagName("form");
  for (var i=0; i<forms.length; i++) {
    forms[i].autocomplete = "off";
  }
}
