Answer 1

What do you mean exactly? I am not understanding your question clearly.

But if you wanna limit maximum number of characters typed in password input - then you can set the 'maxlength' attribute

<input type="password" maxlength="10" />

Reference:
https://developer.mozilla.org/en-US/docs/Web/HTML/Element/input/password

That limits the password up to 10 characters in length. If that's not the question then please edit the question and rephrase it so it will be more comprehensible 👍
