When I bought the AX6000 I was able to use my TP-Link account even when offline to log into this. This was important because my ISP frequently has DNS issues and switching the network to google's public DNS restores internet while they are fixing it.

Recent firmware updates have now displayed a request for a local password. There has never been a local password on this device before. I do not know the local password. It's suppose to be printed on router which it is not. Even if I factory reset the router I will never know what the password is. How do I go about resolving this?
