To recover the password you need to go to nifeislife.com, click "login" and "Forgotten Password?"
Enter your email address associated with your Nifeislife account and wait a few seconds.
You will receive an automatic message with a temporary password to login in your inbox (always also check in Spam). You can change the temporary password by going to the "Change Password" page in the settings wheel (you’ll find it in the upper right corner of the website).
For any further problem with your account you can drop an email to firstname.lastname@example.org
