Thank you always for using our services.

Recently, cyberattacks targeting both companies and individuals have been increasing, and the risk of information leaks and unauthorized access is something that can affect anyone.
To help ensure you can continue to use our services with peace of mind, we have made "Two-Factor Authentication" available, and we recommend that you set it up yourself.

■ About Two-Factor Authentication
Two-factor authentication is a system that, in addition to your ID and password, requires you to enter a verification code displayed in an authenticator app on your smartphone when logging in.
Even if your password were ever leaked somewhere, having this feature enabled can help prevent unauthorized login by a third party.

■ viviON ID Services
Your viviON ID is a shared account used across the following services: 
DLsite / Ci-en / NIJI GAME
comipo / viviON BLUE / GENSEKI

By protecting a single account, you can protect all of these services from unauthorized access.
If you use multiple services, the importance of protection through two-factor authentication becomes even greater.

■ How to Set It Up
Setup can be completed in about 5 minutes from the account management screen.
1. Log in to the account management screen
2. Start setup from the "Two-Factor Authentication" section
3. Install an authenticator app on your smartphone and follow the on-screen instructions

For detailed setup instructions, please see the page below.

■ Especially Recommended For
We especially recommend enabling this setting if any of the following apply to you:
- You use the same password for other services
- You hold important information such as points or purchase history
- You have not yet set up two-factor authentication

We hope you will take this opportunity to consider setting it up, so you can continue to use our services with peace of mind.
