Att smart home manager is being accessed by guests
My Att smart home manager is being accessed by someone connected to my wifi. They have hidden their devices as well so I can not see when they are connected. Is there an option to sign out of all people on my smart home network and limit only me as the administrator. Is there a way to show devices that have been hidden? I have reset password to my wifi before. But they get it or reset my router at my home which let's them log in all over again. Please help me.
