On the left-hand side of the screen in the navigation bar, select My Account. This will take you here:
In the menu bar under Details, select the key icon titled Password.
A pop-up window titled Update Password will appear that looks like this:
Type in your new password in the first box. To view your password, select the eyeball icon to the right of the box.
Re-type your new password in the second box titled Repeat Password. To view your password, select the eyeball icon to the right of the box.
Make sure both of your passwords match. If the passwords do not match, a red error bar will appear to indicate mismatched entries.
Once your passwords match and meet the required criteria, a button titled Update Password will appear at the bottom of the window.
Click the Update Password to finalize your password change.
