Protect accounts with MFA and passkeys
Add a second factor — preferably phishing-resistant options like passkeys or FIDO security keys — on email and other valuable accounts.
Why it matters
Stolen or guessed passwords are common. Multi-factor authentication (MFA) makes takeover harder. Phishing-resistant methods such as FIDO/WebAuthn passkeys bind the sign-in to the real site, which helps against fake login pages that can bypass weaker MFA.
Practical steps
- Turn on MFA for email, banking, Microsoft 365 / Google Workspace, and other high-value accounts.
- Prefer passkeys or FIDO security keys where the service offers them; they are phishing-resistant compared with SMS codes.
- If passkeys are not available yet, use an authenticator app. Avoid SMS as your only second factor when a stronger option exists.
- After enrolling a stronger method, remove or disable weaker fallbacks (such as SMS) when the service allows it.
- Keep a recovery plan your organization approves — for example a spare security key or documented recovery codes stored offline.
