I really strongly agree that the current messaging suggests that you should only use it if you don't trust the other person, and that it's at least partly caused by the 'prenup' language. But as a tagline, "2fa for sex tapes" doesn't really get you to a positive message.

An alternative: "The safest way to share your most intimate moments." It takes what is a deeply troubling problem (revenge porn) — and turns it into an opportunity for deeper intimacy with your partner. Then hit em with value props:

* Protect your intimate videos from hackers — the videos can only be accessed on specific devices.

* Get control over your image. Share your videos as few or as many times as you'd like, and simply delete your video from your Rumuki app to remove access immediately, forever.

* Make security the default. Sent videos can be seen once. Unless you say so, no hacker, ex, or snoop can open it again.
