I'd take it one step further and install OSSEC as well. It can be configured to run as a local daemon and report suspicious activity, and also intervene. So if somebody is brute-forcing the login on your web page, it'll create a burst of 401s which OSSEC will detect in the logs and block the offender for X minutes/hours. Source: over 2 years ago

2FA apps such as Google Authenticator and Authy randomly generate a code every minute or so, which is matched to a specific key associated with your login. In essence, this means that whenever a login asks for your 2FA code, it knows which number to expect and will only unlock if that correct number is entered. Source: 5 months ago
