Fires once the admin request has been validated or not.

$action string

The nonce action.

$result false|int

False if the nonce is invalid, 1 if the nonce is valid and generated between 0-12 hours ago, 2 if the nonce is valid and generated between 12-24 hours ago.

The filter hook is applied in the default check_admin_referrer() function after the nonce has been checked for security purposes; this allows a plugin to force WordPress to die for extra security reasons. Note that check_admin_referrer is also a “pluggable” function, meaning that plugins can override it.
