When signing in to a page using a password manager. The password managers fulfill the required field, and the page automatically triggers the login action.
How does the page knows that the password managers has fulfilled the fields? My login form doesnt recognize when this happens.
I have a basic login form.
<form action="login.php" method="post">
<input type="text" placeholder="Username" name="uname" required>
<input type="password" placeholder="Password" name="psw" required>
<input type="submit" value="Submit">
</form>
