In addition to 2FA security with email, we should also regularly change email passwords and set a long password and have hard to remember characters. The ability to remember passwords is easily compromised.
Another good suggestion is to use a password manager, it is very difficult to come up with passwords that are very difficult to break for a hacker and that are easy to remember, so it is better to use a password manager that can create a password so long and complex that is going to be impossible for any hacker to break it and if you change them regularly then the protection of that password is even stronger.
