SMS is better than nothing yet vulnerable to SIM swaps and interception. Authenticator apps raise security with time‑based codes, while hardware keys resist phishing by verifying the site’s origin. Pick hardware keys for crucial accounts, authenticator apps for general use, and reserve SMS for emergencies. Layer wisely, keep spare keys safely stored, and document setup so future you can recover without panic.
Attackers abuse push notifications to exhaust users into tapping allow. Enable number‑matching prompts, location clues, and rate limits where offered. Pause and ask, “Did I just log in?” If not, deny and change that password immediately. Build a habit: deliberate taps only after intentional logins. This tiny pause defeats many modern attacks while barely slowing your day. Security should feel mindful, not frantic.
Print or securely store backup codes the same day you enable two‑factor, then test one on a low‑risk account so recovery feels familiar. Keep a copy offline in a safe place, away from devices. While traveling, carry a sealed envelope or a secure password manager note. When your phone breaks or goes missing, prepared backups turn a crisis into a minor inconvenience.
Instead of typing secrets into forms, you approve a cryptographic challenge bound to the real site. No shared password means nothing reusable to steal. Even a perfect fake page fails because the origin mismatch stops the handshake. The experience feels familiar—face, fingerprint, or PIN—yet the security leap is huge. Start with accounts that fully support passkeys and enjoy fewer prompts and stronger protection.
Enable platform passkeys on your phone and laptop, then add a hardware key as a durable backup for travel or repairs. Confirm cross‑device syncing is end‑to‑end encrypted, and enroll at least two authenticators per account. Practice recovery on a low‑risk service first. Document steps in your password manager notes so future upgrades are painless and everyone in the household stays aligned.
