Using QR code is really transparent and trusted medium of keychain without any fault. I have already set my all post for 100% power up so I hardly checked auto stake but it is really a good option for the users.
The most interesting thing that I found in keychain is, an easy process of using various website without hivekeys like holozing, steem engine,golemoverlord,hiveblocks that hardly open with chrome.
Really remarkable application.👍👍🙏🙏
