老虎令牌-Tiger Authenticator is a free Android application that provides an added layer of security to the Tiger Trade app. It is developed by TIGER BROKERS and falls under the category of Business & Productivity with a subcategory of Finance. With this app, users can easily buy stocks in the US and Hong Kong markets through Tiger Trade and ensure the safety of their assets.

The app uses 2-step verification, where users need to enter a dynamic password generated by the app along with their login/transaction password. This ensures that the login and order pages can only be accessed when both passwords are verified. The dynamic password is updated every 30 seconds, which provides a more secure account protection experience. Additionally, users can bind multiple accounts to one token without the need for switching between them during trading.
