When users open an account with a broker, whether it's on MT4 or MT5, two types of passwords are created: the master password and the investor password (also known as the read-only password).
Master Password is the main password with the highest level of access. It allows for trading, setting, and account viewing on various MT4/MT5 trading platforms. Using the master password, investors can control all operations within their account.
Investor Password (Read-Only Password): Logging in with the investor password allows one to view account trading activities but does not permit trading. This password is useful for checking account status without interfering with the trader's operations, verifying accounts when issues arise with brokers, and sharing trading experiences securely without giving control over the account.
