There are things that I will rarely rarely rarely do in my life.
For example, changing my main email. Adding a new computer. One security feature that is pretty much full proof that I know is delay.
Basically, say I want to add a new device to my Authy account. Say, I am buying a new phone.
That happens like once every 6 months. I don’t mind waiting 7 days for that to happen. Within those 7 days I get a daily email that someone is adding my authy account to other devices.
A lot of hacking counts on speed. Hackers find something and steal money before the actual owners know how to do anything.
Delay-based protection will not only prevent that, but it will also turn all black hat hackers into a cheap white hat.
None of it is done. Authy, for example, allows us to disable adding more devices but it can be disabled. If one device is compromised then a user can add more devices and before the good guys/owners find out, the money is stolen already.
A sample of such scheme is https://www.authy.com/phones/reset/
You can reset and get stuffs but only if you’re willing to wait.
