The second password is called investor password. It is read-only password used to login for observation purposes. You can not close, modify or start any trades, but you can see the real and genuine trading history and even save the trading statement to your computer. Investor passwords are often used by Forex signal services, account managers.
When you have investor password you can copy/duplicate the trades to your account. You need to install and open 2 Metatrader accounts on your computer. Account #1 with investor password will act as the server and account #2 will be the client account. Now you need to run a special software called Local Trade Copier on both platforms and all trades from account #1 will be copied to the account #2.
