Same here. I have several accounts I used for communities, and they were all "@blocktrades" which I was able to change ALL the keys, password and recovery account.
BUT: The two original accounts I used on steem, have recovery accounts of "@steem" and my Owner Keys do not work for them on peakd.com, as user above NOTES!
Active key works, Posting key works, Owner key does not work. I believe I created these accounts before I knew what a Master Key was, or before that even existed, not sure. Assumed I was fine if I had my Owner key, now they don't seem to work on Hive?
