One-Time Passwords are available as a means of further securing your Square Enix account.
What is a One-Time Password?
A "One-Time Password" describes a six-digit number shown on a screen using either a key-ring like the Square Enix Security Token or a smartphone application, such as the Square Enix Software Token.
One-Time Passwords are only usable for a fixed period of time and become invalid once the user logs in, making them exceptionally useful to combat against spyware such as key logging programs.
By using a One-Time Password in combination with your Square Enix ID and password, you will be able to further enhance the security of your account.
For more details, please refer to the "What is a Security Token?" and "What is a Software Token?" below for instructions on how to start securing your account using a One-Time Password.
What is a Security Token?
A security token is a device for displaying One-Time Passwords that will dramatically improve account security. Pressing the button will display a One-Time Password on the device's LCD screen which will provide you the required one-time password needed to access your account.
Square Enix Security Tokens may be purchased from the Square Enix Store for $14.99.
What is a Software Token?
The Software Token is a free smartphone application designed to display One-Time Passwords that will dramatically improve account security. After registering for the service, a One-Time Password will be shown on screen every time the application is launched.
The application can only be used on Square Enix accounts by customers who have purchased either FINAL FANTASY XI or FINAL FANTASY XIV and registered the corresponding registration codes.
