Prevent user to find password through Firebug/Chrome Dev Tools

Question

For the passport input field:

Answer 1

Well it is not possible with current technology. Like others stated, you still can inspect all the client side code and try to manipulate the DOM.

The other solution is to implement like banking login. Randomise the password sequence every time user login. For example if password length is 10, give user three password fields, ask the sequence of password eg. 3rd, 5th, 10th. This will change every time user try to login. And in the server side you compare them.
