I tell my students there are a few, very few really things that should be written down and saved somewhere on PAPER. These include:
- user ID and associated passwords,
- web URL's or IP addresses of special sites such as medical centers, hospitals,
- special hints that some sites want,
- ID numbers or account numbers such as one for Express Scripts,
- Name, model #, IP address, encryption type, admin password, encryption code for the type of encryption you use and when it was last changed
- The MAC address of all your devices including smart phones
- IP addresses of a couple of sites that should always be there such as Google or ********.com so you can check if your DNS server has gone belly up.


Do not use a password saver or any other way to keep them on your PC like in Chrome unless you pick a method and somewhere weird and then still print them out and hide them at home, NOT in your wallet.

For your router, allow only the MAC addresses listed above to access the box and also limit the total number allowed and change the security code about every 30 days or so.
