You enable WP 2FA with email verification. Codes go to wrong email. Old address. Wrong user. That is frustrating because you cannot log in.
A common issue is that WP 2FA uses WordPress user email. If user changed email in profile, plugin still uses old cached email. Or another plugin overrides user email. The plugin is not broken. Email data is inconsistent.
Why WP 2FA Sends Codes to Wrong Email
WP 2FA fetches user email from WordPress user meta. If user has multiple emails (billing email, PayPal email), plugin may pick wrong one. If another plugin changes user email after save, 2FA uses old value. Cache can also cause stale email.
This is not WP 2FA being bad. Email source needs verification.
The Most Common Email Mapping Failures
- User changed email but plugin still uses old one
- WooCommerce customer has different email (billing vs account)
- Another plugin overrides get_userdata() filter
- Cache plugin serves old user data
- User has no email (guest checkout users)
Check user email in WordPress admin.
How to Fix WP 2FA Wrong Email Delivery
- Go to Users → All Users → Edit user
- Check email address (is it correct?)
- If wrong, update email and save
- Go to WP 2FA → Settings → User settings
- Click “Resync user data” or “Clear cache”
- Test 2FA code delivery again
Updating user email fixes most cases.
How to Force WP 2FA to Use Correct Email
Add filter to functions.php:
add_filter('wp_2fa_user_email', function($email, $user_id) {
$correct_email = get_user_meta($user_id, 'billing_email', true);
if ($correct_email) return $correct_email;
return $email;
}, 10, 2);
This uses WooCommerce billing email for 2FA codes.
Alternative: Use Authenticator App Instead of Email
Switch from email 2FA to authenticator app (Google Authenticator, Authy). App does not depend on email address. No wrong delivery. More secure.
Go to WP 2FA → Settings → Methods → Enable “Authenticator App.”
