How to get email on my iphone after changing password?

I changed my password due to a hacking. Now I don't get email on my i phone.

Go into your Settings, then scroll down to Mail, Contacts, Calendars.
The Email Accounts would show up at the top of the screen.
Hit the account (and hit again when the account comes up) and it will take you to the info page. Just type in the new password and hit "done".
