Utopic-R can open your door with single-use or time-limited codes that you create. With this system, called OTP, you can generate codes that are valid for a certain period of time without connecting to your smart lock. These codes, created with high security, can be used for a single entry or unlimited times within a date range you specify. Thanks to these codes, you can have your door unlocked from anywhere via the wireless keypad with OTP capability. Additionally, even without a keypad with the OTP feature, you can send a single-use code to your guest through the Utopic app and have your door unlocked — no need to be near your smart lock or have a connection.
