What Is Two-Factor Authentication for a CMS?
BeginnerQuick Answer
TL;DR
Two-factor authentication (2FA) adds a second verification step after a password — typically a time-based code from an authenticator app, an SMS message, or a hardware security key. Even if an attacker steals a user's password, they cannot log in without the second factor. For any CMS with multiple editors or admin access, 2FA should be mandatory.
Key Takeaways
- 2FA requires a second proof of identity beyond a password, dramatically reducing unauthorized access risk
- Authenticator apps (Google Authenticator, Authy) are more secure than SMS-based codes
- Hardware keys (YubiKey) offer the strongest protection and are phishing-resistant
- All CMS admin accounts should have 2FA enforced — not just recommended
