When shopping online, protecting your home address will prevent your information from being compromised and keep it out of databases
Shopping online involves a trust factor. You have to give merchants accurate information (billing address) in order to make the purchase, and a mailing address to have your order delivered. That is a lot of information to leave on someone’s server for eternity.
Virtual phone numbers are a great way to protect your personal information, protect your privacy, use for 2-factor authentication, and more
Email forwarding provides a layer of protection between you, & the mishandling of your information which exposes all your other accounts. It also helps you control spam in your inbox.
