使用 smtp 通过 PHPMailer 发送 Email 例如提交报价

Question

I need to write a code where user fills a form / submit Quote to a website. As user submit Quote website owner should recieve an email. I used PHPMailer set smtp Host to smtp.gmail.com and sending email from user to owner. It works perfectly fine. But where I have to put password, I am quite confused, that username is the email I get from form but I am not getting any password of sender/user's email. Without putting password in the code I am unable to send email from user. What changes Do I need in my following code to submite Quote properly. Kindly Guide me. Here is my code:

<form action="submitQuote.php" method="post" id="submit-quote">
            <input type="text" name="name" placeholder="NAME" required>
            <input type="email" name="email" placeholder="EMAIL" required>
            <input type="tel" name="phone" placeholder="PHONE" required>
            <div class="select-box">

Answer 1

$mail->Username = "your-email@gmail.com"; //your email address from GMAIL

$mail->SetFrom("from-email@xyz.com", "from-name"); // the email sent by user via form post.
