二段階認証（2-Step Verification）

2 step verification adds an extra layer of security to your account, so we know it’s really you. With 2 step verification, your account will be protected by both your password and information sent to your phone.

Every time you access your account, you will be required to enter your password and a verification code. Depending on which option you select at set up, you will receive your unique code from either Google Authenticator or it will be sent directly to your phone.

You can manage your 2 step verification settings in your account, including managing your ‘Trusted devices’. This feature allows you to add a device to your trusted list which means you will not be required to enter a verification code every time you access your account on that device.
