all the comments here are getting hung up on the encryption.

me, personally, i think you did a hell of a job with this. personally i'm not going to be sharing any launch codes with my spouse, so i could care less about how industry standard and unbreakable the encryption is, but for account based credentials like netflix and spotify, this is great.

also, the landing page is spot on showcasing what this app is and how easy it is to share with others. take a bow dude and i wish you some good fortune.
