About Two-Factor Authentication Apps

An authentication app is an application installed on your computer or smartphone that generates an Authentication Code that is valid for a set period of time.
DLsite offers Two-Factor Authentication via means of an authentication app.
To set up Two-Factor Authentication, you must install an authentication app on your device in advance.
After setting up Two-Factor Authentication, in order to log in, you will need to enter a 6-digit code displayed by the Two-Factor Authentication app you set up, in addition to your login ID and password.

[Authentication App]

Install an authentication app that is compatible with your device. (e.g. Google Authenticator)
* From iOS 15 onward, Two-Factor Authentication can be set up using the built-in password feature, eliminating the need for installing an authentication app in some cases.
*If you set up two-factor authentication using iOS's password function, you'll first need to register your DLsite ID and password on your iOS device.
