For your security, T-Rex requires a password that is secure enough. T-Rex requires customers to use highly secure passwords, avoiding the use of commonly used character strings.

Placing restrictions on customer passwords prevents brute force attacks where passwords of different character sequences are randomly checked for an ID or attacks dictionary in which pre-existing passwords in the dictionary are randomly checked. There is also something called an account list attack where ID and password combinations are stolen from a web service and used in an attack. Please note that the same ID and password should never be used across multiple services.

Two-factor authentication (2FA) can be set by SMS, email address or GA authentication application. For regular services, login is achieved through ID and password authentication. However, when connected to the internet, this service can be accessed from anywhere, and because of that security can be broken when ID and password pairs are stolen or a malicious third party get ID and brute attack or dictionary attack. This is where, in addition to the original ID and password, an additional six-digit number known as the authentication code is entered, thus enhancing security. Because the authentication code changes over time, as well as whenever a login occurs, even if a malicious third party steals the ID and password, it will be more difficult to gain access.

Each time you log in to T-Rex, a login confirmation email/SMS will be sent to your registered email/SDT address from T-Rex containing a link to freeze your account. your. This is done so that in the event a third party logs into your account, you can immediately freeze your account. Additionally, once you've logged in, you'll be able to confirm your login history, including your IP address, date and time, and device type.

To prevent unauthorized activities by third parties, you will be logged out in case there is no activity for a certain period of time.

When you login to T-Rex, if you enter incorrect password 10 times, your account will be locked. This is to protect customer accounts from attacks such as brute force attacks.

For example, in the event that there is even a small amount of inconsistent data in a customer's Bitcoin deposit balance, the system will be forced to shut down to minimize the damage. In the event of a minor failure, the system is designed to respond quickly to prevent greater damage.

T-Rex applies information security and control standards according to Iso27001 version 2018 to ensure absolute safety for the system and end-user information.
