OTP – Authentication Using One Time Password

Use of OTP (one-time password) provides an additional level of security when working with trading accounts. The user is required to enter a unique one-time password every time to connect to an account.

  • The use of OTP should be enabled on a trade server.
  • The forced use of OTP can also be enabled on a trade server.

One-time passwords are generated in the mobile platform for iPhone and mobile platform for Android devices.

How to Enable OTP

To use One Time Passwords, you should bind your trading account with the password generator, which is the mobile platform for iPhone or Android devices.

Go to the Settings of the mobile platform and select OTP. For security reasons, when you first open this section, you will be required to set a four-digit password. The password must be entered every time to access the password generator.

Set a password to access the OTP generator

In the window that opens, select "Bind to account".

Bind the account to the OTP generator

Next, specify the name of the server on which the trading account was opened, the account number and the master password to it. Keep the "Bind" option enabled. Disabled it, if you are going to unbind the specified account from the generator and stop using One Time Passwords.

Tapping on the "Bind" button located at the top of the window binds the trading account to the generator. An appropriate message appears after that.

Using OTP

Likewise, an unlimited number of accounts can be bound to the generator.

The one-time password is displayed at the top of the OTP section. A blue bar below visualizes the password lifetime. Once the password expires, it is no longer valid, and a new password will be generated.

Additional Commands:

  • Change Password – change the generator password.
  • Synchronize Time – synchronize the time of the mobile device with the reference server. Accuracy requirement is connected with the fact that the one-time password is bound with the current time interval, and this time should be the same on the platform and the server side.

After binding a trading account to the generator, a one-time password will be additionally requested when connecting to it from the desktop platform:
