MFA: the cheapest security upgrade you can make
Why multi-factor authentication stops the majority of account attacks, and how to roll it out across your business.
If you do one thing for your security this month, make it this. Multi-factor authentication (MFA) — a second step beyond your password — blocks the overwhelming majority of account-takeover attacks, because a stolen password alone is no longer enough to get in.
Why it works
Most break-ins don't involve "hacking" — they involve a password that leaked in some other breach and was reused. MFA breaks that chain: even with your password, an attacker can't pass the second factor sitting on your phone.
Where to turn it on first
- Email — it's the master key; whoever controls it can reset everything else.
- Banking and payments.
- Admin panels for your website, hosting, and cloud accounts.
- Your password manager.
Do it well
- Prefer an authenticator app or a hardware key over SMS codes (SMS can be intercepted).
- Turn it on for every employee, not just leadership.
- Save backup codes somewhere safe so a lost phone doesn't lock you out.
Rolling MFA out across a team without disrupting everyone is one of the quick wins we handle in a hardening engagement.
