How our e-mail password stores in to our system ?

When we log out our password is taken out of the system and there is no place where we can actually see our password.
Almost any service we use (gmail, rediffmail, yahoomail etc) has the option to REMEMBER our password so we do not have to enter it when we sign in to a particular site. In this case all we will see is "xxxxxxx".
The below description is how we can  REMOVE those that are remembered, but if we read it correctly it shows us where to go if we do want them remembered.

INTERNET EXPLORER :

Click on TOOL...INTERNET OPTIONS...CONTENT TAB. Once in go below and click on SETTINGS for Auto Complete. Click on "delete autocomplete history" and then OK. Once this is done you might want to place a check mark in the box to the left of "user names and passwords on forms" AND "ask me before saving passwords". That way you can save the passwords you want and deny those that you do not. Then click OK. .

FIREFOX : 

Click on TOOLS...OPTIONS....PRIVACY TAB...go below and make sure there is a check mark in the box to left of "clear history when Firefox closes" and then click on SETTINGS. Place a check mark in the box to the left of "saved passwords"...click OK
There may be times you want to save passwords so you can click on TOOLS...OPTIONS ..SECURITY tab...go below and place a check mark in the box to the left of "remember passwords for sites"..click OK. You will be given options of remembering this password or not.

GMAIL :
