I bet they mean like in wordpress where the cookie will be set for a year instead of a week? 
What’s the bbpress cookie default, I’ll have to go look at the code.
I get around this problem by forcing the wp login from everywhere.
There was another request for this feature here:

		This plug has been causing trouble lately. When it’s installed, when the existing cookie expires, no one can log in at all. I have to go deactivate it in order to allow people to log in again.
Is there an update for the most recent versions?
		
	 
	
	
	
 
		
			
	
	
		
		Delete the plugin, just put <input name="remember" type="hidden" id="quick_remember" value="1" /> in your login-form.php file.
		
	 
	
	
	
 
		
			
	
	
		
		Of course things will break when you use the alpha (which you failed to mention).
I’ve updated it to 0.0.2 to deal with the mess in bbPress 1.0
