A reasonable alternative for non-technical people.
I was contemplating another benefit of using email forwarders (aliases) recently. I realized that most people probably have only one email address, and not only do they use it for their personal email, but also as their User ID / logon for all kinds of accounts, including social media and banking. The User ID should really be treated as a secret the same way as password and secondary backup questions & answers. If you advertise your email address to the world, you’re giving away half of the information required to logon to your other online accounts. You’re also giving someone half of what’s required to get into your inbox, which can cause all kinds of havoc if you use one email address for everything. It would allow the hacker to bypass any multi-factor authentication that sends an email with one-time codes for password resets or for logins from new devices.
Using separate email addresses for all online User IDs and using them exclusively can keep them secret. Even better if those addresses are not fully fledged email accounts, but are forwarders / aliases that just forward the email to another, completely secret address. Even if a hacker obtained your forwarder, they couldn’t login to your email.
The best way to do this is to get your own domain ($10-$15/yr) and web hosting ($3-$10/mo) with unlimited email accounts and forwarders. It’s not easy though.
