Why SMS 2FA is Vulnerable to SIM Swapping
SMS authentication relies on SS7 mobile carrier networks, allowing attackers to bribe or social-engineer telco reps to route your phone number to their SIM card. App-based TOTP (Google Authenticator) or FIDO2 WebAuthn keys are impervious to SIM swapping.
Knowledge Check
Which of the following is the most secure multi-factor authentication method?
This module is guided content rather than a processing tool. It walks you through steps on the systems you already use, and nothing about your setup is sent to us.
No single tool makes an account or a device secure. This module reduces one specific category of risk. It does not detect malware already running on your device, it cannot recover data you lose the key to, and it does not replace keeping software updated and using unique credentials everywhere.
If your device itself is compromised, anything you type into any tool — including this one — can be observed. Treat device hygiene as the foundation everything else sits on.
