In other words, to change your actual email account password, you'll need to first go through the email provider to update your credentials, and then make the change in Mac OS X. Mac Mail Tip: if you change your email password inside Mac Mail, it will only affect the application itself, not your email account.

Apple Mail will exit the Preferences window, and return to your emails from this point on, Mac OS X will store the new and updated email password in your keychain.

Once you are done, click on the Close button or press ' Esc' on your keyboard, and choose ' Save' from the confirmation dialog Mac Mail shows when asking ' Save changes to the '' POP/IMAP account?' (or simply click on the ' Don't save' button to keep your current password and return to Mail.app).

Since Mac Mail doesn't let you see what you type, and doesn't offer a second password field to confirm, pay particular attention to avoiding any typos (a wrong password will generate error messages when you try to check for new messages or try to send one.) Double-click inside the password field to select the current password, and start typing over it your new password.

The middle section of that tab starts with your ' Incoming Mail Server', and ' User Name', and includes a single ' Password' text field further below.

Once you see your email account information loaded on the right part of the Preferences window, make sure that the ' Account Information' tab is selected (should be by default).Click on the email account whose password you want to change (if you only have a single email account, it is already selected). Once the Mail options dialog opens, select the ' Accounts' tab: Mac Mail will display all email accounts currently setup inside the application.Once you are inside the email program, click on the ' Mail' menu in the top left corner of the screen, and choose ' Preferences' from the dropdown (or press ' Cmd+,' on your keyboard).First, launch Mac Mail by clicking on its icon in the dock or typing ' Mail' in Spotlight.This is how you change the stored email password in Mail for Mac OS X: (if you want to change the actual user account credentials for your Mac, see how to change password on Mac OS X).
