I love this concept. Being able to seamlessly just “view” the world (or an app, or a place - in the case of Satlantis) through the eyes of another is very cool

And then choosing to log in (or unlock?) using YOUR keys, as and when you want, is a beautiful way to manage your access to applications 

 "Unlock" is some good language right there! Might use that 👀  

 I want people to discover this feature so much. I need them thinking "What if I click on this other Jack?" and then have their mind blown 😂
