in uno script che ho è necessario che negli imput si mettano le password del database per accederne e modificarne il contenuto

<input type="password" name="password" />

codice:
password:  Like "text", but the input text is rendered in such a way as to hide the characters (e.g., a series of 
asterisks). This control type is often used for sensitive 
input such as passwords. Note that the current value is the 
text entered by the user, not the text rendered by the user 
agent.

    Note. Application designers should note that this 
mechanism affords only light security protection. Although 
the password is masked by user agents from casual observers,
it is transmitted to the server in clear text, and may be read by anyone with low-level access to the network.
