Good point. Although I think that works best for clients where people can directly get active. Nosta is about setting up your basic profile and then using other clients to fill that profile up further. So the user needs to have the key to sign in elsewhere. 

TBH, I have not quite figured out how to make that really smooth. Installing a browser extension during profile setup seems like a good step forward. It's in a way more complex to set up, but at least the private keys follow along to other clients and users just need to confirm pop-ups. Maybe Nosta needs a minimal browser extension companion for key handling?
