To change your Stratosphere password, click on "Change Password"
Enter your current password then your new password, twice. Click on "Update Password" to complete the change.
Note: There are no requirements as to what you make your password. You should, however, choose a password that is relatively difficult to guess. A good, strong, secure password would have at least seven characters. It should include a combination of upper and lower case letters, numbers and special characters. It should never be based on a dictionary word, a name or date--all of which could easily be guessed.
