Date:Jul 10, 2026How to Find Your MT4 Investor Password on Desktop (Windows and Mac)
The fastest way to find your MT4 investor password on desktop is inside the platform itself: open the Terminal window (Ctrl+T), select the Mailbox tab, and open the message titled Registration (usually the first mail you received). If that message is not there, check your broker welcome email or your broker client area, or set a new investor password under Tools > Options > Server. This guide walks through all four methods in detail. The steps are the same on Windows and Mac.
Using the MT4 app on your phone instead? Follow the dedicated guide for Android or for iPhone, where every step matches the app screens. There is also a MT5 guide available.
One thing to know before you start: MT4 never displays an existing investor password in its settings. You can only read it where your broker originally issued it, or replace it with a new one. That is why the four methods below are ordered from fastest to fallback.
What is the investor password in MT4?
Every MT4 trading account supports two passwords. The master password (also called the main or trading password) gives full access: it can place, modify, and close trades. The investor password gives read-only access: anyone logging in with it can see the balance, open positions, and full trade history, but the server blocks every trading action.
The investor password exists so you can share your trading results without handing over control. It is what fund managers give their clients, what prop firm traders use to share verified track records, and what analytics tools ask for when they connect to your account. TradeMedic™ AI connects with the investor password only, which means it can read your trade history to analyze your behavioral patterns but can never place a trade.
One detail that trips up many traders: not every broker creates an investor password automatically. Some issue it together with your login at account opening. Others leave it empty until you set one yourself. If the first three methods below come up empty, that is usually why, and method four solves it in under a minute.
Method 1: Check the Mailbox inside MT4
When a broker creates your account, its server usually sends a registration message directly into the platform. This message contains your login number, server name, master password, and investor password. It stays in the platform mailbox even if you deleted the welcome email years ago, which makes this the single most reliable place to look.
Open MT4 and log in to your account.
Press Ctrl+T to open the Terminal window at the bottom of the screen (or go to View > Terminal).
Click the Mailbox tab.
Look for a message titled Registration or New Account Registration and double-click it.
Metatrader 4/5 Find Investor Password Guide Screenshot 1The message lists your login, server, master password, and investor password. If you see several registration messages, match the Login number to the account you want to connect.
If you trade in the browser-based MT4 web terminal, note that it does not include the Mailbox. Check your broker welcome email or client area instead.
If there is no registration message, your broker either did not send credentials into the platform or did not generate an investor password at all. Move to the next method.
Method 2: Check your broker welcome email
Most brokers send account credentials by email when the account is opened. Search your inbox for the broker name combined with terms like “account details”, “login”, “MT4”, or “welcome”. The email typically lists the login number, server name, and both passwords. Check the exact account number if you hold more than one account with the same broker.
For prop firm accounts, this email usually arrives right after you purchase a challenge or receive a funded account, and the investor password is often listed there under a name like “read-only password” or “investor access”.
Method 3: Check your broker client area
Log in to your broker’s client portal and open the section that lists your trading accounts. Many brokers display the investor password there, or offer a button to reveal or reset it, without opening MT4 at all. Prop firms almost always show account credentials in the trader dashboard next to each account.
Method 4: Set a new investor password in MT4
If the password was never issued or cannot be found, set a fresh one. This requires your master password, the one you normally use to log in and trade. Setting a new investor password does not affect the master password or any open positions.
Log in to MT4 with your master password.
Go to Tools > Options in the top menu (or press Ctrl+O).
Open the Server tab.
Click the Change button next to the password field.
Enter your current master password in the top field.
Tick the option Change investor (read only) password.
Enter your new investor password twice and click OK.
The MT4 web terminal does not offer an investor password change; use the desktop platform or your broker client area.
Is it safe to share your MT4 investor password?
Yes, within its purpose. The read-only restriction is enforced by the broker’s server, not by the app on the other side. Whoever holds the investor password can watch the account but cannot open, modify, or close a single trade, and cannot touch settings or funds. To let a person or tool view your account, share three things: the login number, the server name, and the investor password. Never share the master password with anyone.
Two sensible habits: change the investor password from time to time if you share it often, and treat it like any credential rather than posting it publicly. Read-only still means anyone with it can see your full trading history.
This server-side restriction is exactly why TradeMedic™ AI asks for the investor password and nothing more. The connection can read your trade history to detect your behavioral patterns across 60+ dimensions, and it is technically unable to trade on your account.

Frequently Asked Questions
Can someone place trades with my MT4 investor password?
No. The investor password gives read-only access enforced by the broker’s server. Trading, withdrawals, and settings changes are blocked regardless of which device or app is used to log in.
Why is the Change button greyed out when I try to change the investor password?
You are most likely logged in with the investor password itself. Read-only sessions cannot change account settings, and MT4 shows a “not enough rights” error or disables the button. Log out and log back in with your master password, then repeat the steps.
My broker never sent me an investor password. What should I do?
Some brokers do not generate an investor password automatically. Set one yourself using method four in this guide, and confirm the change with your master password. It takes under a minute.
What is the difference between the master password and the investor password?
The master password gives full control of the account, including placing and closing trades. The investor password gives view-only access to the balance, positions, and history. They are independent: changing one does not affect the other.
Does a MT4 demo account have an investor password?
Usually yes. When you create a demo account inside MT4, the final screen shows both passwords, and the registration message in the Mailbox contains them too. A few brokers issue demo accounts without an investor password, in which case you can set one the same way as on a live account.
Can I find my MT4 investor password on my phone?
Yes. The MT4 mobile app contains the same Mailbox and the same password settings. Follow the dedicated guide for Android or for iPhone on this blog, where every step matches the app screens.
My investor password is not working when I connect to a tool. What is wrong?
The three most common causes: the login number or server name does not match the account, the password was changed at some point and the old one is being used, or the master password was entered by mistake in a field expecting the investor password. If in doubt, set a fresh investor password and reconnect with it.
Connect your account with read-only access
Once you have your investor password, connecting your MT4 account to TradeMedic™ AI takes a few minutes: enter your login number, server, and investor password, and the analysis of your trading behavior across 60+ patterns starts on data the connection can only read, never trade on.
