Sounds like you need a different ISP. Home network and router should use every single digit allowable by the router hardware and any guest access, should have severely restricted permissions. In my opinion, your computer should have two primary loggin accounts even if you only have one user (yourself), as the ability to come up on an uncorrupted account with permissions can be handy for cleaning if successfully attacked or locked. This was very handy back in the days of ransomware that could lock you up. Both loggins should be a reasonably complex password and the days of turn on and go without password is long gone. Guest accounts for router network or computer should have almost no privileges at all beyond restricted internet/network and maybe printer. On the email account, that password should be max length and complex, as you almost never use it after established and max security does not get in the way. If you can travel without a password book or card, you probably are not, using enough security. Is your email using your name? No need for it to be. My email is a random sounding acronym with meaning only to me, as I do not share my name on the internet with every jackoff that wants me have access to something. Not really a paranoid old fk. I just don't share personal identifying information randomly on the World Wide Web of the internet. Mobile devices should utilize biometric. Just my opinion.
