2 step authentication just went live for PlayStation accounts in North America and Europe.
After going live with the security feature in Australia and New Zealand a few days ago, 2 step authentication is now live for PlayStation accounts in Europe and North America. Information for the feature hasn’t gone live yet but it will be viewable here when it goes live. To activate 2 step on your account, visit this page. 2 step authentication is a feature every service should have as it is one of the best security measures against unauthorized access. One thing to note is you will not be able to use apps like Authy or Google Authenticator for generating codes.
