Hello @icaro SteemConnect is the safest way at the moment to login other Steem applications with your Steem credentials. Utopian does not store anywhere your credentials. Also SteemConnect is based on this repository, owned by Steem itself: https://github.com/steemit/sc2. You are totally safe. Get in touch with me for any doubt. I will help you write your first Contributor Report on Utopian.
