Stop Using SMS 2FA

Why Your OTP is Not Safe

By RecOsint | Dec 3, 2025

Your Phone Number is the Key. You think your bank account is safe because it sends a code to your phone. But what if the hacker becomes you? They don't need your phone; they just need your Phone Number.

The hacker calls your mobile carrier (T-Mobile, Verizon, etc.) pretending to be you. – The Lie: "I lost my phone, please move my number to this new SIM card." – The Glitch: If the support agent believes them, your signal dies instantly.

What is SIM Swapping?

They Get Your OTPs Now, the hacker's phone has Your Number. > Result: When they try to login to your Gmail or Bank, the "Forgot Password" OTP goes to THEM, not you. > Damage: They can drain bank accounts and steal social media handles in minutes.

Stop relying on SMS. Use an App-based generator. – Apps: Google Authenticator, Authy, or Microsoft Authenticator. – Why: These codes are generated locally on your device. Even if your SIM is stolen, the hacker cannot see the code.

Use Authenticator Apps

SMS is better than nothing, but it is the weakest link. – Action: Go to your Facebook/Google settings today and switch 2FA from "SMS" to "Authenticator App". – Tip: Set a PIN code with your mobile carrier.
