Roast my idea: An app that lets people send files that the recipient can only open by verifying their face.

Basically the title.

You send a file, and the other person has to scan their face to make sure it's them (for eg. I could integrate Face ID) to open it.

Passcodes, passwords, e-mail access (think one time link sent to email to open) could be hijacked easier than one's face.
