One-Time Use Pins

Create single-use pins for delivery personnel like Uber Eats or Amazon, ensuring privacy and security.

Instant Door Notifications

Receive real-time notifications  for all door events, including when the door is opened, wrong pin entries, and more.

Ok, but how does it actually work?

Update

Replace your current cellphone number with the new Number Provided by Knocker in your building intercom system.

Use
