What is investor password?

What it means

Every MetaTrader account has two credentials: the master password, which can trade and withdraw, and the investor password, which can only look. Handing over the investor password lets someone audit the account without being able to touch it, which is what makes independent verification possible at all.

Why it matters

This is the mechanism behind Myfxbook and every similar service, and it is what a serious buyer should ask for. A vendor who will not supply read-only access to the account behind their claims is declining the one check that costs them nothing and proves the most.

What this changes in practice

The safety limits are worth knowing precisely. Read-only access cannot place, close or modify orders, and cannot withdraw. It can see full position and balance history, and on some brokers it is enough to identify the account holder. It is safe to share for verification and it is not anonymous.
