I don’t know what the conditions are inside, but I’m assuming that people need light in there to work, and that if it’s designed to be disaster or attack resistant, there would be a need for climate control, ventilation and flooding mitigation. I get that the venue is chosen because it should keep everything frozen and preserved, it just depends how fragile / robust they’ve built it.

But I wondered because I can see light coming from inside and it looks like there’s a fancy light show on it.

I wonder what the power source for that vault is.

I use passkeys through 1Password and it’s vastly less irritating to me than anything involving passwords, especially 2fa. I really don’t like having to wait for email to arrive or copying down digits from a text message, which seems to be how 2fa typically works 90% of the time.
