The OTPCredential interface of the WebOTP API is returned when a WebOTP navigator.credentials.get() call (i.e. invoked with an otp option) fulfills. It includes a code property that contains the retrieved one-time password (OTP).

This interface also inherits properties from Credential.

OTPCredential.code Experimental

The OTP.

OTPCredential.id

Inherited from Credential. The ID of the credential type.

OTPCredential.type

Inherited from Credential. Always set to otp for OTPCredential instances.

None.

None.

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.

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