this site is in test mode, so if you aren't comfortable with that, then yes, please continue using other sites.
i'm not sure what you are referring to, however, since if you login on desktop it is intended to work just like peakd and should open hive keychain for approval.
login on mobile only works if you use the hive keychain internal browser at present.
the next build of ureka will operate exactly the same as peakd etc. in terms of login for mobile.
