How to Change MT5 Master Password or Investor Password?

If you know your current password, you can change it directly through the MT5 trading platform:

Desktop (Windows / Mac)

Click "Tools" → "Options" → "Change". Enter your current master password to modify the master password or investor password (changing the investor password does not affect the master password).

Mobile (Android)

Tap the account you want to change the password for, select "Change Password" and follow the prompts.
