Account takeovers and SIM swapping attacks have surged dramatically in recent years. Safeguarding your accounts requires a layered defense.
- Key Recommendations:
- Avoid Permanent Personal Numbers: Never expose your primary personal phone number on public forums, classifieds, or experimental web apps.
- Use Dedicated Verification Numbers: Provision isolated single-use non-VoIP lines for one-off service tests.
- Enable Time-Based OTP (TOTP): Where supported, combine SMS backup routing with hardware security keys or authenticator apps.
- Monitor Webhook Telemetry: Set automated alerts whenever a verification attempt fails or times out.
