Internet service in multiple locations (STR)?

[Will Fraser]

I'm working on scaling my STR holdings and with the mainstream ISPs I am required to set up a new username for service at each new place. At 2 units that was okay. At 4 it's getting complicated, and thinking of 10+ makes me angry in advance.

How do you manage having internet service at multiple locations?

I am equally frustrated by this, but I don't have a silver bullet. Your only hope to keep organized with a password app that is secure. Keep all your passwords stored in the app, along with keypad door codes, padlock combos, and any other data for the STR. I wish AT&T had a "multi-account" function.
