The Most Expensive Lesson of My Life: Details of SIM Port Hack
I&#x27;d like to see more companies introduce &quot;time locks&quot; into various big aspects of accounts.<p>Want to port a SIM? I&#x27;ll put your request in now but it will wait for 5 business days before it happens, and at any point if you or someone claiming to be you calls up to stop it, we stop it, no questions asked.<p>Want to change 2 factor information for an account? We can put in the request now and it won&#x27;t take effect for a week while we reach out to you using every communication method we know how to let you know it&#x27;s happening and give you ample time to stop it if you discover it wasn&#x27;t actually you that did it.<p>It seems like a fairly &quot;low cost&quot; way of upping the security quite a bit.<p>Also, not to make the OP feel worse, but Coinbase even offers a service like this called the &quot;vault&quot;. The idea being that withdraws are time-locked for a specific amount of time, and there are multiple ways to stop it during that time lock, even if you got locked out of your account entirely.<p>And while we are doing PSAs, I&#x27;d like to give one piece of seemingly conflicting advice: make sure you have backups of your multi-factor authentication systems.<p>Sure, having your accounts taken over is awful, and it can happen to anyone, but something just as bad is losing your 2-factor systems and being locked out of accounts with no way to recover them.<p>Print out 2-factor backup codes, put them somewhere safe, maybe split them in 2 and put half of the codes in one place, and half in another. Think through possible problems. It really sucks to have your house flood, then find out that your phone with the 2-factor app on it was destroyed, and your backup codes ruined as well...
