In order to protect your account and avoid any potential theft of your assets, KuCoin uses Google Authenticator. This protects your KuCoin account and adds an extra layer of security.
All users have passwords to their accounts, but passwords alone aren't safe. They can also easily be stolen. For this reason, we require users to use Google Authenticator and bind the Google two-step authentication to their account. Once users' accounts are bound, even if their password is stolen, the user's phone or secret key is still required to log in to the account.
The Google two-step verification code is generated by the Google Authenticator on the phone, and the verification code is changed every 30 seconds. Each verification code can only be used once.
