SIM Swapping: When SMS Fails

SIM swapping is a targeted attack where a hacker convinces your mobile carrier to transfer your phone number to their device. Once they control your number, they receive your SMS codes.

This is why security experts recommend authenticator apps over SMS. The codes are generated on your device and never travel over a network, making them immune to SIM-swapping and network interception. Apps like Authy or Google Authenticator are free and simple to set up.
