Why is there only a 30 day recovery window if someone has the keys? If someone has the original master/owner keys, shouldn't they be able to always recover their account, proving they were the original owner of the first keys generated on the account?

I'm new(ish) to Steemit, but I also thought that the master/owner key was never able to be changed?

Speaking of keys, where can I go now to get a copy of all my keys? The option had popped up for me a long while ago when I had tried to login using my master key, I had to get my posting key and change the details in my password manger. I should have but I did not copy the details for my other keys then, and now I can't find the option to.
I use SteemKeychain now, which takes care of everything but I know the importance of having backups.. I don't want to be screwing around in KeyChain to copy the keys, and I don't think it's showing me all my keys either, is there another way?

Thanks for any help you can provide.
