Oh, man, this might help you out alot.

I guess you don't have keychain, then.

Hiveauth is nearly as good.

When you go to peakd.com you will see a number of different sign in methods.
Peakd has their own version of a key manager and is as safe as the others.
You can put your keys in it and not have to worry, but I think it only signs you in on their interfaces.
Peakd has more features than wallet.hive.blog, but doesn't host the internal market.

I'm not sure were to get started, so feel free to ask questions as you come across them.
