Email/SMS Verification (OTP)

Email/SMS Verification OTP adds a simple one-time password step to WordPress login. After entering username and password, users receive a 6-digit code via email or SMS. They enter this code to complete login, adding a second verification factor without requiring authenticator apps. Simpler than full 2FA for users who find apps confusing, while still providing meaningful security improvement over passwords alone.

Frequently Asked Questions

Is this different from 2FA?

OTP is simpler than full TOTP 2FA. Codes are sent, not generated by an app. Easier for non-technical users.

Can I use both email and SMS?

Configure the delivery method in settings. Email is default, SMS requires an SMS gateway integration.

How long are codes valid?

Codes expire after a configurable time period, typically 5-10 minutes.
