# How to Set Up Two-Factor Authentication (2FA)

## How to Set Up Two-Factor Authentication (2FA)

To further strengthen security, let's set up two-factor authentication (2FA) for your account. This will greatly reduce the risk of unauthorized access to your account, even if your password is compromised.

## How Two-Factor Authentication (2FA) Works

When signing in to Ptengine, a one-time password issued from an authenticator app on your smartphone will be required, enhancing security. When signing in, you will need to enter a confirmation code that changes every second along with your password. Since we use an authenticator app to receive authentication codes, please follow the steps below to install and configure it.

## Setup Steps

**Download and Install an Authenticator App** Before setting up the 2FA feature for your account, first download [Google Authenticator](/en/faq/others/two-factor-auth.md) and install it on your device.

**Access Account Settings** Log in to Ptengine and access "Change Password" from Account Settings.

\*\*Enable Two-Factor Authentication \*\* Click the \[Two-Factor Authentication] button.

Then, scan the QR code displayed in the admin panel with your smartphone's authenticator app, or obtain the key code and manually enter it into the app.

\*\*Enter Confirmation Code \*\*On the next 2FA setup screen in the Ptengine admin panel, enter the 6-digit confirmation code generated by the authenticator app. Click \[Enable Authentication] to complete the setup.

## **How to Log In to Ptengine After Setup**

When logging in to Ptengine, open the authenticator app and enter the code along with your password each time.

If you delete the authenticator app or lose your phone, you will temporarily be unable to register, but please be sure to request the removal of two-factor authentication by emailing <cs@ptmind.co.jp> from the **registered account email address**.
