## AI-driven attacks and the stakes

AI is helping attackers [research vulnerabilities, develop exploits, and automate attacks faster and at greater scale](https://cloud.google.com/blog/topics/threat-intelligence/ai-vulnerability-exploitation-initial-access). It also helps criminals produce convincing messages, imitate familiar voices, and tailor scams to individual targets. [The FBI has warned that AI makes fraud more believable and easier to produce.](https://www.ic3.gov/psa/2024/psa241203) Polished language and a plausible story are no guarantee that a message is genuine.

Security keys cannot fix software flaws, but they can help protect a common target: your login.

The stakes are personal. Your primary email often receives the password-reset messages for your other accounts. Losing control of it can give an attacker a route into much more of your digital life. Financial accounts carry the more immediate risk of stolen money. Cloud storage holds private documents and photographs. These are accounts worth protecting before something goes wrong.

## The weaknesses of SMS codes

A password plus a six-digit text message is better than a password alone. But text-message codes can be stolen through [phishing](https://en.wikipedia.org/wiki/Phishing) or [SIM swapping](https://en.wikipedia.org/wiki/SIM%5Fswap%5Fattack), where an attacker takes control of your phone number and receives your verification texts.

A fake sign-in page can collect your password and code, pass them to the real service, and let the attacker capture the authenticated session. Authenticator-app codes avoid the SIM-swapping risk, but they can still be stolen and relayed through phishing. [NIST does not consider manually entered codes phishing-resistant.](https://pages.nist.gov/800-63-4/sp800-63b/authenticators/)

## Why security keys and passkeys help

Modern physical security keys (such as a [YubiKey](https://www.yubico.com/products/yubikey-5-overview/)) and passkeys change that exchange. Instead of asking you to type a code that someone else could steal, they provide proof tied to the legitimate service. [A lookalike website cannot use that proof to sign in to the real one.](https://developers.google.com/identity/passkeys)

A hardware key is a small device you plug into a computer or tap against a compatible phone. Passkeys can also live on your phone or computer, without a separate key. Both offer phishing-resistant protection where supported, reducing the need to recognize every convincing fake login page.

Many people already use these protections at work because their employer requires them, yet never consider applying the same protection to their personal accounts. Their primary email, financial accounts, and private files deserve that attention too.

## The responsibility that comes with stronger security

These protections also deserve some homework. Understanding what happens if a key or device is lost, what backup options exist, and how account recovery works is part of using them safely. Removing familiar fallback methods without understanding the alternatives can leave you locked out. Recovery options differ across services.

Keys and passkeys will not stop every scam, repair an infected device, or protect a session already stolen by an attacker. They address an important weakness in how we sign in.

As AI makes deception more convincing, learning about these options is time well spent. Your email provider, financial institutions, and other important services are good places to find out what they support. Better personal security starts with understanding the choices and deciding which protections you can use and maintain reliably.
