Change saved password on iPhone

If you have stored a password in Safari on your iPhone and would like to change or remove it, tap the Settings icon on your home page: 

Scroll down and tap Passwords: 

Scroll down the list until you locate smartmls.com (it should display your user name):

Your saved user name and password will appear (your password will be a series of dots, but in this image it has been blanked out). Tap Edit:

Backspace through the current password, enter your new one and tap Done.
