Not sure what to enter for INFINOX My Account and for MT4/MT5? You are not alone.
There are two entrances. Account management uses your registered email address and password. MT4/MT5 use your account number, password and server name.
This is based on the official FAQ (checked 17 October 2026). By the end, you will know the steps and what to do when an error appears.
Conclusion: INFINOX has two login entrances
- My Account (client area): sign in with your registered email address and password
- MT4/MT5: sign in with the account number, password and server name in your welcome email
- MT4 and MT5 are separate trading accounts. One account cannot be used on both
- IX App and IX Social: use your main INFINOX login. MT4/MT5 use a separate sub-account
- The actual server name is not stated in the official FAQ. Use the welcome email and the client area display
The official pages say "client area" and "Client Portal". The login button leads to myaccount.infinox.com, so this site writes "My Account (client area)".
How to log in to INFINOX My Account
- 01Press "Login" on the official site
Use the button in the header of the INFINOX Japanese site. The login screen is on the domain myaccount.infinox.com.
- 02Enter your email address and password
Use the email address and password you registered when opening the account. The official FAQ also describes access with these two.
- 03Open "Trading Accounts"
The official MT5 page says you can also check your login details under "Trading Accounts" in the client area.
When you open the page from a bookmark, always check the domain. Avoid entering your password on a page you reached only through an email link.
The 3 details you need for INFINOX MT4/MT5 login
| Item | What it is | Where to check |
|---|---|---|
| Account number | The number of your MT4 or MT5 trading account | Welcome email / client area |
| Password | The password for MT4/MT5 | Welcome email (reset in the client area) |
| Server name | The server you connect to | Welcome email (the actual value is not stated in the official FAQ) |
※ After you open an account, your MT5 login details are sent to your registered email address (official MT5 page). If you cannot find the email, check the client area.
- 01Choose the trading account login from "File"
Start MT4/MT5 and go through the "File" menu.
- 02Enter the 3 details
Type the account number, password and server name from your welcome email.
- 03Tick "Save account information"
This makes the next login faster. Untick it on a shared computer.
According to the official FAQ, one account cannot be used on both MT4 and MT5. Each needs its own trading account, and both can be managed under the same INFINOX profile.
In a browser, you can log in through WebTerminal. For Mac, there are dedicated apps for both MT4 and MT5, which you can download from the client area.
IX App vs MT4/MT5: how the logins differ
| Entrance | Login details | Main use |
|---|---|---|
| My Account | Registered email address + password | Checking trading accounts, password reset, deposits and withdrawals |
| IX App / IX Social | Main INFINOX login | IX App for trading, deposits, withdrawals and account checks; IX Social for copy trading |
| MT4/MT5 | Account number + password + server name | Trading. Account management such as deposits and withdrawals cannot be done inside the app |
※ To trade on MT4 or MT5, create a dedicated sub-account in the IX App or Client Portal. IX App and IX Social do not need a separate login for each app.
Logging in to the IX App does not take you into MT4/MT5. MT4/MT5 are entered separately, with the sub-account's account number, password and server name.
Resetting your INFINOX password
- 01My Account password
On the login screen, choose "Forgot password". A secure reset link is sent to you by email automatically.
- 02MT4/MT5 password
In the client area's platform settings, select the account and press the key icon, "Reset MT4/5 password". Follow the on-screen instructions to set a new password.
You can change the Investor (read-only) password from the MT4/MT5 options window (Ctrl+O). On the Server tab, press "Change" and enter the master password to continue.
What to do when you cannot log in to INFINOX MT4/MT5
| Message | What to check |
|---|---|
| Invalid Account | Check that the account number, password and server name match your opening email. If it is not solved, reset the password in the client area |
| No Connection | Check that you chose the right server and that your internet connection works. Check that a firewall or antivirus software is not blocking it |
- Did you enter an MT4 account number in MT5? They are separate trading accounts
- Did you type the account number and server name from the email without leading or trailing spaces?
- Did you mix up your My Account password and your MT4/5 password?
If the checks above do not fix it, use the contact form on the official site. Include your account number and the error shown. Only official support can check your individual account status.
