"Off the Grid" in the '90s:
- Forage your own water
- Forage, hunt and grow your own food
- Generate your own electricity
"Off the Grid" in the current year:
- Use a VPN, rotate IP addresses
- Use burner phones to verify online accounts
- Does not use free email providers
Regarding the use of burner phones to verify online accounts - it is not necessary. There are services that provide a free number to receive a text or receive and record a call for you. I verify all of my accounts like that, they even have country specific numbers.
