It creates new, randomized access codes every 4 hours.
Wyze Lock Bolt generates a couple of randomized access codes that can be used once. Need to let someone in temporarily but don't want to share your full-time code?
In the Wyze app, go to your Wyze Lock Bolt > Settings > One-Time Code.
You can use that code in the keypad temporarily. You don't even need Wi-Fi or Bluetooth, and you don't even need to be close to home.
