"API Password missing"in logs

“16-04-27 07:07:16 homeassistant.components.http: API password missing or incorrect. Source IP:xxx.xxx.xxx.xxx”
This message starts showing in log

I guess there is some timeout for logins. Not an issue is you select save password but I do see this as an issue for below:

-User cannot tell when this condition occurs. UI updates and show normal for most components.
-some component error out; i.e. cameras will not show image

Other than saving password. Is there another way to kick user out when expired and force them to login again?

I am seeing this same error, even though I have saved my password.
