How to Set Up Two-Factor Authentication (2FA) on Every Account

If I could force everyone to do one single thing for their security, it would be enabling two-factor authentication on every account. I have hardware YubiKeys on my keychain, authenticator apps on my phone, and 2FA on literally every service that supports it. Even when my credentials have appeared in breach databases, 2FA stopped attackers cold every time. This guide walks you through setting up 2FA on every major platform, explains which types are actually secure (hint: not SMS), and gives you my priority list for which accounts to lock down first.
