Hi. It works the same as on Steem. You need the master key (I think) to reveal your keys. Really you should change them to be different to what you had on Steem. That needs the master key too. Plus you should change the recovery account to someone other than Steem just in case they pull more dirty tricks. This post has some info on it.

Just tried to see my keys at https://wallet.hive.blog/@steevc/permissions and it prompts me to log in. I use Keychain, but it still doesn't work. Maybe something is wrong.

Anyway, change your keys when you can and keep a safe backup.
