30 day password expiration

Hi

Having trawled through the Plug-in directory over the past few days, was just wondering whether anyone knew of a plug-in which creates a
password protected section of the site for members.

Now I know there are, but we need the initial password to be active for 30 days only and then it’s discontinued – so they are going to be permitted access for 30 days and after that it will be determined by membership type.

Many thanks in advance.
