I think I misunderstood your requirements. If you also want to share your account with others, it's not for you.

Amber is only for Android. You will be able to log into installed apps and websites on your phone. I used to use nsecbunber for the same purpose.

But if you want to share an account with someone else, it's not the replacement for that.  

 makes sense, I feel like I would’ve known if there was a true nsecbunker alternative out there /:
