Setting up / disabling 2-step verification – POSTYPE Help Center

🌐 This article has been translated from Korean for your convenience. If there is any discrepancy, the Korean version prevails.

What is 2-step verification?

Each time you log in with email, you enter a code sent via an authentication app to verify your account, which provides an extra layer of security.
2-step verification is not supported for social logins (Google, Naver, Facebook). Please use the login/verification features provided by each social service.

How to log in with 2-step verification

Enter your username (ID) and password.
Enter the 2-step verification code generated by your authentication app.

Setting up 2-step verification

[My Menu] > [Settings] > [Account] and turn on the ‘2-step verification (OTP authentication app)’ button under Security Settings.
Enter your password to verify your identity.
Install an OTP authentication app (Google Authenticator, Authy, etc.) on your device.
- Install Google Authenticator: iOS / Android
- Install Authy: iOS / Android
Enter the 2-step verification setup key (16 characters, uppercase letters and numbers) generated in the POSTYPE app into your authentication app.
Once your POSTYPE account and the authentication app are linked, click ‘Next’ and enter the verification code generated by the authentication app.
Click ‘Done’ to activate 2-step verification. To protect your account, automatic login will be disabled and you will be logged out on all devices and browsers.

Disabling 2-step verification

Go to [My Menu] > [Settings] > [Account] and turn off the ‘2-step verification (OTP authentication app)’ button under Security Settings.

Checking your one-time backup codes

If you lose your device or delete your authentication app and can’t access your 2-step verification codes, you can log in using a one-time backup code.
Go to [My Menu] > [Settings] > [Account], click ‘View one-time backup codes’ under Security Settings, and enter your password to see your one-time backup codes.
Each one-time backup code can only be used once when logging in.
We recommend saving them as a screenshot or storing them separately in a safe place.
On the login screen, click ‘Verify with a one-time backup code’ at the bottom to enter a one-time backup code.

I can’t complete 2-step verification.

If you saved your one-time backup codes separately, you can log in using a one-time backup code.
If you did not save your one-time backup codes, please contact the Help Center.

It says 2-step verification is required.

When an account is accessed from too many devices, POSTYPE requires 2-step verification. This is to keep your account safer and to prevent account sharing with others.

If you follow the on-screen instructions to complete 2-step verification, you can log in normally and continue using POSTYPE. Without 2-step verification, your account use will be restricted, and for security reasons we cannot disable this mandatory 2-step verification requirement.

If you did not share your account and have not used it on 3–4 or more personal devices, we recommend additional security measures such as changing your password. For more details, please see Personal information and account protection guidelines.
If you are sharing your account or using a shared account, please stop account sharing immediately. If you continue to violate our Account Trading Policy and we detect ongoing account sharing, we may take additional actions such as account suspension, permanent restriction of use for the same identity, and legal measures.
