Complete Email OTP Flow

  const [email, setEmail] = useState('');
  const [otp, setOtp] = useState('');
  const [isVerifying, setIsVerifying] = useState(false);

  const handleSubmit = async (e) => {
    e.preventDefault();
    setIsVerifying(true);
    
    try {
      const result = await verifyOTP({ otp, email });
      
      if (result.success) {
        // Handle successful verification
        console.log('OTP verification successful');
        // Redirect or update UI
      } else {
        console.error('Verification failed:', result.message);
      }
    } catch (error) {
      console.error('Verification error:', error);
    } finally {
      setIsVerifying(false);
    }
  };

  if (!isLoaded) {
    return <div>Initializing verification...</div>;
  }

  return (
    <div className="otp-verification">
      <h2>Verify Your Email</h2>
      <p>Enter the 6-digit code sent to your email address.</p>

      </form>
      
      {verificationError && (
        <div className="error-message">

Auto-Submit OTP

function AutoSubmitOTP() {
  const { verifyOTP, verificationError } = useVerifyEmailOTP();
  const [otp, setOtp] = useState('');
  const email = 'user@example.com'; // From context or props

  // Auto-submit when OTP is complete
  useEffect(() => {
    if (otp.length === 6) {
      handleAutoVerify();
    }
  }, [otp]);

  const handleAutoVerify = async () => {
    try {
      await verifyOTP({ otp, email });
    } catch (error) {
      console.error('Auto-verification failed:', error);
    }
  };

  return (
    <div>
      <input
        type="text"
        value={otp}
        onChange={(e) => setOtp(e.target.value.replace(/\D/g, '').slice(0, 6))}
        placeholder="Enter 6-digit code"
        maxLength="6"
      />
      
      {verificationError && (
        <p className="error">Invalid code. Please try again.</p>
      )}
    </div>
  );
}

Notes

  • OTP codes are typically 6 digits and expire after a short time
  • The hook handles the verification API call and manages loading states
  • Email verification is commonly used for account confirmation and password resets
  • Failed verification attempts may be rate-limited for security
  • Always validate OTP format on the client side before submission
