Goal

What the Team Set Out to Achieve

Durin wanted to give homeowners a secure, intuitive way to validate who is crossing their threshold without relying solely on traditional methods like PIN codes or physical keys. The goal was to create a voice-based backup authentication experience that felt natural, was universally understandable, and complemented Durin’s multi-factor approach to access control. At the core, the solution needed to be more secure than common backup options, easy to use for a broad range of users, and seamless to integrate into Durin’s smart home platform.​

Challenge

What Stood in the Way

Providing home-owners a secure, multi-factor way of validating the identity of those who are crossing their threshold is one of Durin’s key promises. Durin looked to Sensory for a method of authenticating identity that went beyond PIN codes, and was more secure than other solutions on the market.

Outcome

What Changed After Implementation

Durin successfully introduced a spoken passphrase backed by Sensory’s voice verification as a backup method for smart home access. Homeowners gained a more secure, natural-feeling alternative to PINs and hidden keys, aligned with Durin’s promise of safer, smarter entry experiences.​

Key outcomes included:
  • Improved confidence in backup authentication
  • A more intuitive, human-centric access experience
  • Hands-free convenience at the threshold

Highlights

Why This Case Stands Out

  • A modern “open sesame” experience that feels culturally universal
  • A smarter alternative to common, less secure backup methods
  • A more human, confidence-inspiring way to control home access
  • A strong, collaborative partnership focused on usability and security​

Conclusion & Testimonial

Sensory’s voice authentication felt like the missing piece at the threshold. It gave us a backup method that’s secure, human, and universally understood—proving that even ‘open sesame’ can evolve for the modern smart home.
