How to Lock Biometric Machine Settings: Admin Guide to Prevent Unauthorized Access

Biometric machines are used to record employee attendance—but did you know that anyone can access the settings if the machine is not protected?

This guide explains how to lock your biometric device menu so that only authorized admins can access it—while everyone else can still mark their attendance as usual.

This feature is supported in almost all major brands, including:

✅ Cams Biometrics
✅ ZKTeco
✅ eSSL
✅ Suprema
✅ And many more…

🔐 What Does the Lock Do?

The menu lock does not stop users from giving attendance.

But it blocks access to the device menu, which contains:

User management
System settings
Network setup
Logs and reports

With this lock enabled, only admin users can enter the menu using their fingerprint, face, card, or password.

👣 How to Set the Lock (Step-by-Step)

You only need one admin user to activate the lock. Here’s how to do it:

1️⃣ Add or Edit a User

Go to the device and:

Create a new user, or
Select an existing user

2️⃣ Set as Admin

In the user settings:

Find the option called “User Type” or “Privilege”
Change it from Normal to Admin

By default, all users are added as normal users unless you change this.

3️⃣ Enroll Access Method

The admin must save at least one way to unlock the menu, like:

Fingerprint
Face
RFID Card
Password
(This depends on what the machine supports.)

That’s it! Once an admin is added, the menu will lock automatically.

🧪 What Happens Now?

When someone tries to enter the menu, the machine asks for an access key.
If a normal user tries, access is denied.
If an admin user applies their fingerprint/face/card/password, access is granted.
