Two-factor authentication is critical, but not every user wants to install an authenticator app. Email-based 2FA provides the same security boost using something everyone already has: their email inbox. After entering their password, users receive a code via email to complete login.<\/p>\n","feature_full_description":"

Sometimes your phone is dead, or you're on a new device without your authenticator app, or you just prefer email. Email-based Two-Factor Authentication provides flexible security that meets users where they are.<\/p>\n

Here's how it works: After entering their password, users receive an email with a one-time verification code. Enter the code, and they're in. The code expires after 15 minutes and can only be used once.<\/p>\n

This makes 2FA accessible to everyone-no apps to install, no devices to sync. It's particularly valuable for:
\n\u2022 Clients who aren't tech-savvy
\n\u2022 Emergency access when the primary 2FA method isn't available
\n\u2022 Sites where requiring an authenticator app would create too much friction<\/p>\n

Security note: Email 2FA is slightly less secure than TOTP because email accounts can be compromised. For highest security, we recommend TOTP with Email as a backup option.<\/p>\n","feature_benefits":["No additional apps required","Users already know how to use email","Perfect backup when authenticator isn't available","Quick setup-just verify email address","Codes expire automatically for security"],"how_it_works":["User enters username and password","Stack Guard sends a 6-digit code to their registered email","User checks email and enters the code","Login completes successfully","Code expires after 15 minutes or first use"],"feature_use_cases":["Sites with non-technical users","Backup 2FA method for emergency access","Organizations where app installation is restricted","Users who prefer email over apps"],"protects_against":["Password theft","Unauthorized access","Account takeovers","Credential stuffing"],"feature_faqs":[{"feature_faq_question":"Is email 2FA as secure as authenticator apps?","feature_faq_answer":"TOTP apps are slightly more secure since codes never leave your device.
