If you wish to change your account password at this time, you'll need to remove your account from Email and then re-add it:
- Tap the list view icon in the top-left corner
- Tap "Settings"
- Select the email address you wish to remove from the list at the top
- Tap "Delete Account" and confirm
- From the previous screen, tap "Add Account" and re-add your email address with your updated password
While updating your account passwords isn't easier at the moment, we hope to simplify this process in the future.
