Does e-mail ID remains in the computer?

The e mail id and password will be stored in the computer if you clik the chek box "remember" So never clik this box if you are using a computer which has got access by any other person

agree with boby g,

I agree with above opinion also for comlete protection you may delete the browsing history and select 'everything'. Then Every details will go.

When you say computer, it is only hardware like monitor, keyboard, cpu etc.  It will not be stored in the computer. e-Mail ID means the address of the person in cyberspace.  Unless you reveal your ID to others they would not know about your e-Mail address and they would not be able to communicate with you.  Your password is what matters.  If others come to know of your password, they can open your e-Mail box in cyberspace or the data of the e-mail stored in your hard disc when you browse.  It can be stolen by certain theft softwares called keyloggers. As you go on typing your password to open your e-Mail inbox, the thief would be recording the same in his computer by using the keylogger stealthily fixed in your e-mail.
