Why do we need to change trading account password? There are several factors such as:
If you have a clear reason to change the account password, then the execution is very easy to do, you just need to open the Metatrader application, search Tab Navigator, right click on the Account you want and select Change Password menu.
Next will appear column:
Current password = Please type the existing password
New password = Please type a new password
Confirm = Please type a new password (again to confirm)
There are 2 types of passwords: Master Password and Investor Password. Master Password is the primary password used for trading, while Investor Password is ReadOnly account (can not execute trade) which is only used to monitor trading activity only.
Note: Sometimes the broker asks for a complex password that is a combination of capital letters + lowercase + numbers.
