Abstract Abstract
The Extensible Provisioning Protocol (EPP) includes a client The Extensible Provisioning Protocol (EPP) includes a client
authentication scheme that is based on a user identifier and authentication scheme that is based on a user identifier and
password. The structure of the password field is defined by an XML password. The structure of the password field is defined by an XML
Schema data type that specifies minimum and maximum password length Schema data type that specifies minimum and maximum password length
values, but there are no other provisions for password management values, but there are no other provisions for password management
other than changing the password. This document describes an EPP other than changing the password. This document describes an EPP
extension that allows longer passwords to be created and adds extension that allows longer passwords to be created and adds
additional security features to the EPP login command and response. additional security features to the EPP login command and response.
