MFA Is Mildly Annoying. A Rerouted Payroll Deposit Is a Lot Worse.

The trade is straightforward. Multi-factor authentication costs you a few seconds and a small irritation each time you log in. Skipping it can cost you an account, the data behind it, and in the worst case, money that does not come back. Stated that flatly, the few seconds start to look like a bargain. The annoyance is real. It is also tiny next to what it prevents.

A password alone is a single lock

Passwords leak constantly, through breaches, reused logins, and convincing fake sign-in pages. At this point, betting that yours has stayed secret is less a security plan and more a hope. Once someone has a password, a single-lock account is wide open. Multi-factor adds a second lock that lives on something you physically have, like your phone. A stolen password on its own becomes close to useless, because the attacker is missing the second piece and cannot get it from a data dump.

What the worst case actually looks like

Picture an email account with no second lock. Someone gets in with a leaked password and simply watches for a while. When a real invoice comes through, they step in, change the bank details, and the payment sails off to them. Or they get into a payroll system and quietly reroute a direct deposit. By the time anyone notices, the money is gone and the cleanup is brutal. A second lock stops this at the front door.

The annoyance is the point, a little

Yes, it adds a step. That friction is doing real work. It is the difference between an attacker needing only a stolen password and needing your physical phone too. Modern options keep the hassle small: an app that pushes a quick approval, codes that take seconds. The mild inconvenience you feel is the same wall the attacker cannot climb.

Worth the few seconds

Turn on multi-factor authentication everywhere it is offered, starting with email, banking, and payroll, because those are the accounts that turn into real losses. The few seconds it adds to your day are the cheapest insurance you will ever buy against the very bad afternoon it prevents.
