Tanya Jawab

Does this replace my existing password?: No. Users must enter their normal username/password first, then OTP.
What happens if the OTP email does not arrive?: Make sure your site can send emails. We recommend configuring an SMTP plugin for reliable email delivery.
Can I change OTP expiration time?: Yes. In the plugin class, $otp_expiration controls OTP lifetime (default 300 seconds = 5 minutes).
Can I use this with WooCommerce login?: This version is built for native WordPress login. In next release, I will add WooCommerce support.
Is OTP stored securely?: Yes. OTP is stored using the same mechanism WordPress uses for user passwords.
