MyFitnessPal Data Breach Impacts 150 Million User Accounts

MyFitnessPal parent company Under Armour today announced that MyFitnessPal has been the victim of a hacking incident, which has seen personal details of approximately 150 million user accounts accessed in a data breach.

MyFitnessPal is a popular health and fitness iOS app and website that’s used by many iPhone and iPad owners, and it is consistently among the top Health and Fitness apps in the App Store.


The breach, which happened in late February, included usernames, emails, and encrypted passwords. Social security numbers, driver license numbers, and credit/debit card information were not accessed.

Under Armor has already been sending emails and in-app messages to its customers who were affected by the breach. The company says it is working with “leading data security firms” to assist in its investigation.

MyFitnessPal users will be required to change their passwords.
