A strong password does not prevent account hacking.

• The hacker can put a keylogger in your computer and very easily collect all the password you type.
  I remind you that the keylogging if a feature of Windows 10. Everything you type in this system is reported to Microsoft.

• Every browser ask you to store your password. This kind of storage is very unsecured. You can very easily recover your password stored in this way.

I think that 2 factor authentication is a must when it comes to protect your fund. You should use either U2F (FIDO) or TOTP authentication.
U2F authentication requires you to push the button of your usb authentication key that's It. It's quick and simple.

A U2F key costs less than 10 $.
