Abstract
An intermediate network device includes a local caching module that caches user information from a remote server before a local user requests the information. In particular, the local caching module securely obtains and caches one-time passwords for a local user. The local caching device maintains separate sets of one-time passwords for each user. The local caching module may access the locally cached one-time passwords to authenticate a local user to a resource protected by a one-time password.
