Auto copy to text box?

[Connor9220]

I've been using this for some time, and noticed that in many sites, after I click on my code, it auto-copies to the MFA field on the website. I'm also a developer and maintain a application. It has MFA, and this doesn't happen on this site. What attributes or causing this to happen? What do I need to do on the website to make this work?

Here's our logic for autofill:

Authenticator/src/content.ts

Lines 285 to 323 in 9d9660b

	function pasteCode(code: string) {
	const _inputBoxes = document.getElementsByTagName("input");
	const inputBoxes: HTMLInputElement[] = [];
	for (let i = 0; i < _inputBoxes.length; i++) {
	if (
	_inputBoxes[i].type === "text" ||
	_inputBoxes[i].type === "number" ||
	_inputBoxes[i].type === "tel" ||
	_inputBoxes[i].type === "password"
	) {
	inputBoxes.push(_inputBoxes[i]);
	}
	}
	if (!inputBoxes.length) {
	return;
	}
	const identities = [
	"2fa",
	"otp",
	"authenticator",
	"factor",
	"code",
	"totp",
	"twoFactorCode",
	];
	for (const inputBox of inputBoxes) {
	for (const identity of identities) {
	if (
	inputBox.name.toLowerCase().indexOf(identity) >= 0 ||
	inputBox.id.toLowerCase().indexOf(identity) >= 0
	) {
	if (!inputBox.value || /^(\d{6}|\d{8})$/.test(inputBox.value)) {
	inputBox.value = code;
	fireInputEvents(inputBox);
	}
	return;
	}
	}
	}

Okay, I tracked down the problem. It's the fact that the mfa field is in a iframe page.
