I also didn't know that the public keys all start with STM. Interesting.

I let the password manager save the posting and active keys since they are easy to change if compromised and you get a little lag time heads up in terms of if the active key were suddenly used to power down your account.

But yeah, also that master password needs to be sure not to be lost. That's the other danger. Backing it up in just enough places is a good idea.
