MFA Is the Biggest Security Win for the Least Effort

The scariest breaches are the quiet ones. An attacker phishes one employee's username and password, logs in, and walks straight into your network with no alarms going off, because as far as the system can tell, it is that employee. The single highest-impact fix for this is multi-factor authentication. Turning it on does more to lower your risk, for less money and effort, than almost anything else you can do. Here is how to roll it out, from good to best.

Start with authenticator app codes

The baseline is a one-time passcode from an authenticator app on the user's phone. After the password, they enter a short code that changes every thirty seconds, so a stolen password alone is no longer enough. Use the app rather than text messages where you can, because codes sent by SMS can be intercepted. This step alone stops the large majority of account takeovers.

Make it easier with push approval

To cut the friction, push-based authentication sends a simple approve-or-deny prompt to the phone instead of a code to type. It is faster, and people actually use it. One caution. Attackers will spam those prompts hoping someone taps approve out of fatigue, so pair it with number-matching and train people to reject anything they did not start. Convenience and care, not one or the other.

Aim for phishing-resistant methods

The strongest option ties authentication to the device and the person, biometrics and passkeys, often called phishing-resistant MFA. Because there is no code to steal or prompt to trick, even a convincing fake login page comes up empty. It is where security is heading, and worth moving toward for your most sensitive accounts now.

Whatever level you start at, the important thing is to start. MFA is the rare security upgrade that is cheap, fast, and genuinely moves the needle. We run it across our own accounts, including the administrator logins attackers want most, because we are not willing to bet the business on a password alone.
