I trust https://v2.steemconnect.com/ which looks like it redirects to there, so seems OK. No third party application (even steemit.com) is 100% safe though - technically. There is always a very slight risk when entering your keys into any website. Some are a lot safer than others though, and Steemit + SteemConnect are both sites I trust.
Do you know if SteemConnect.com is trustworthy?
