The code read-only property of the OTPCredential interface contains the one-time password (OTP).

Value

A string containing the OTP.

Examples

The below code triggers the browser's permission flow when an SMS message arrives. If permission is granted, then the promise resolves with an OTPCredential object. The contained code value is then set as the value of an <input> form element, which is then submitted.

js
navigator.credentials
  .get({
    otp: { transport: ["sms"] },
    signal: ac.signal,
  })
  .then((otp) => {
    input.value = otp.code;
    if (form) form.submit();
  })
  .catch((err) => {
    console.error(err);
  });

Note: For a full explanation of the code, see the WebOTP API landing page. You can also see this code as part of a full working demo.
