Lock screen & PIN

The badge protects access with a numeric PIN. While locked it shows the lock screen; unlocking requires the correct PIN. This page covers locking and unlocking, changing the PIN, and the lockout and auto-lock behaviour.

Locking and unlocking

Unlock: from the lock screen, press any key (except 3, which opens the lock-screen menu) to open PIN entry, type your PIN with 0–9, and press Y. A correct PIN opens the main menu. The badge ships with a default PIN of 123456.

Lock: press N repeatedly to back out of all menus to the lock screen. The badge also locks itself automatically (see Automatic locking).

Changing the PIN

Open Settings → Change PIN. This runs a three-step wizard:

1. Current PIN — enter your existing PIN. It is verified before you can continue. The screen also shows the number of remaining retries.
2. New PIN — enter the new PIN.
3. Confirm PIN — re-enter the new PIN. It must match step 2.

In the wizard:

• 0–9 add a digit, Y confirms the step.
• N deletes the last digit. On an empty first step it cancels the whole wizard; on a later step with no digits entered it goes back one step.
• If the confirmation does not match, the wizard returns to the New PIN step.

PIN length

The badge PIN must be between 4 and 8 digits long. Y will not accept a PIN shorter than the minimum, and entry stops at the maximum length.

Wrong PIN and lockout

The badge allows 3 attempts. Each wrong PIN clears the entry and decrements the remaining retries (shown on screen). When the retries reach zero the badge enters a 60-second lockout: PIN entry is blocked and the screen shows a countdown. After the lockout expires the retry counter is restored and you can try again.

Note

The retry counter is held in RAM and the lockout timer runs from boot, so a power-cycle during the lockout does not permanently brick the badge PIN.

Automatic locking

After 5 minutes of inactivity, the badge automatically returns to the lock screen, requiring the PIN again on the next use. (A foreground plugin that requests to keep the badge awake suppresses this auto-lock while it is active.)

For the instant rescue lock, see the anti-block chord under Keypad & input methods: holding N and Y together forces the badge straight back to a clean locked state.

Duress PIN

In addition to the normal PIN, the badge supports an optional duress PIN that wipes the device when entered. It is set up separately and is disabled by default. See Duress PIN for details.
