Introduction

Today I answer some of the most interesting listener questions from the past several months, including: how to do you get SMS 2FA codes while traveling abroad; should I periodically change all my passwords; how do hackers attack IoT devices inside my home network; can a website fingerprint me based on a hardware security key; can you recommend an email client that protects your privacy; if I give my IoT device permission to see my local network, does that include the guest network; how to hackers find vulnerabilities and figure out how to attack them; why can’t I use my VPN on an airplane to stream Netflix; how can I protect my cryptocurrency and smartphone. Also, I give my take on the crazy TikTok ban legislation.
