Use Rental Numbers for Important Accounts

Rental virtual numbers are generally more suitable than temporary numbers for accounts that may require future verification or password recovery.

Enable Multi-Factor Authentication

Whenever supported, enable multi-factor authentication to provide stronger account protection beyond SMS verification.
