How to protect yourself from SIM swapping
It's easier than you think for someone to convince your carrier that they are you and get them to port your number to their device in order for them to get your two-factor authentication (2FA) codes in order to bypass your security. We all know by now that using SMS for your 2FA is a very bad idea, and instead you should use an authenticator app (like Google Authenticator or this open-source alternative). But there's a simple step you can take to prevent this by locking your SIM with a PIN so that you can protect yourself from this nightmare scenario which could allow a hacker to drain your bank account or steal your identity.
