How can i change the login page to a custom one.. I whant to support two way authentication so users need to enter a one time password after entered the username and password. At the moment i have done it with a rewrite rule like this..

<add name="adminrewrite" virtualUrl="^~/umbraco/login.aspx"      rewriteUrlParameter="ExcludeFromClientQueryString" destinationUrl="~/umbraco/login2.aspx" ignoreCase="true" />

and set rewriteOnlyVirtualUrls="false" in the urlrewritingnet ofcores i can delete de login.aspx file and place my own but if i whant to upgrade i need to be sure the file is not overriden.

a option override the default login.aspx would be nice..

also custom property's for the backend users would be great so i can store te private keys direct at the users
