Total Security 2018 Vulnerability Scan Problem

KC9

Can someone help me out on below?

The vulnerability scan says I don't have a router password for my Asus router RT-AC68U however I do have a strong password for the router login. I understand this is not referring to the wifi network password which I agree the scan says the password is weak.

It reads

MAC address: xx-xx-xx-xx-xx-xx

Password strength: No password

Your router access is unsecured. We recommend......

Change outer password

The router's password is stored in the browsers cache. To protect your privacy......
