You will receive an e-mail containing your login credentials as well as an Investor Password when you create a regular ECN Live Account. That password is solely for mentors to monitor your trades and is a Read-Only password. 

When you create a PAMM Investor account, you will receive a separate e-mail with the login credentials to join a Fund. To invest in a Fund, you'll need the credentials contained in this e-mail (Account No and the Trader Password).
