[pmwiki-users] Limiting access to the last entered password

[Randy]

Happy New Year,

I resolve to improve my wiki's security. :)

I want my login form and any pages it (:includes:) to have access to  
the last entered password, but turn off access outside of that. I  
tried the following, but it didn't do what I expected:

if ($action == 'login') $FmtPV['$AuthPw'] = 'reset(array_keys((array)@ 
$_SESSION["authpw"]))';

Is it possible to limit access to the last entered password?
