Passcodes are an essential part of managing access and security with the BLACK X smart lock system. The app offers flexible options to generate and customize passcodes for various needs.

The length of the generated code is automatically determined by the system algorithm, based on the expiration period and the complexity of the recurrence. Shorter expiration periods result in shorter codes, while longer periods produce longer codes. The length typically ranges from 6 to 11 digits.

When setting up a code, you can select the “Custom” option to specify a validity period or choose an unlimited duration. Additionally, you have the flexibility to create a code of your choice, ranging from 4 to 9 digits — ideal for using a memorable number.

How to Create a Passcode

To create a code, follow these simple steps:

1. Open the BLACK X app.
2. Go to the Main Menu.
3. Select Keypad Code.
4. Choose the desired lock for approval.
5. Click Generate Code.
6. From the top bar, select the desired period length.

Note: You can choose Custom to manually create a code.

1. Enter the required information.
2. Click Set a Passcode to complete the configuration.

After configuring the code, you can send it to the authorized user via SMS or Email. Simply click “Notify via SMS” or “Notify via Email” to share the code.

Verification Code Timing

If you’re experiencing delays in receiving the verification code via email, don’t worry! The 45-second countdown you see is just the waiting time before you can request a new code—it doesn’t mean your current code is expiring. Your original verification code remains valid for one hour, giving you plenty of time to enter it once it arrives.
