# Signing in to the register

> Unlock the register with your PIN, find your card in the roster, and switch users during service.

Once the device is paired with your store (see [pairing a device](/en/setup/pairing)), the register shows the roster screen on startup. Every team member signs in with their own PIN, so sales and actions are attributed to the right person.

## Who appears in the roster

The **Who's working?** screen lists every team member added to your store in the backoffice — servers, cashiers, managers, and owners. Each card shows the person's name and role.

You add or remove team members from the backoffice, in the [Staff](/en/backoffice/staff) section.

<Note>
  A new team member can take up to 30 seconds to appear on the register after
  being added in the backoffice. The list updates automatically — no need to
  restart the app.
</Note>

## Signing in

<Steps>
  <Step title="Tap your card">
    On the **Who's working?** screen, tap the card with your name. The PIN
    screen takes over, showing your name and the message **Enter your PIN to
    open the register**.
  </Step>

  <Step title="Enter your PIN">
    Type your code on the keypad. Sign-in confirms automatically as soon as
    you enter the last digit — there is no confirm button. Staff members have
    a 4-digit PIN; managers and owners a 6-digit one.
  </Step>

  <Step title="You're on the register">
    The selling screen opens right away. On the first sign-in of the day, the
    register may prompt you for [start of day](/en/pos/start-of-day).
  </Step>
</Steps>

If the PIN is wrong, the screen briefly flashes red, then resets. Enter your code again.

## Signing in as a manager

At the bottom of the roster screen, the **Sign in as manager** button opens a **Manager sign-in** window listing only manager and owner accounts. Tap your account, then enter your 6-digit PIN.

## Switching users

* From the PIN screen, tap **Switch user** at the top left (or swipe from the left edge) to go back to the roster.
* Once signed in, tap **Log out** at the top right of the selling screen to hand over. The register returns to the roster, ready for the next person.

Open orders are not lost when you sign out: they stay visible in [the orders list](/en/pos/orders-list) for the whole team.

## Automatic lock

After 10 minutes without interaction, the register locks itself and asks for a PIN again. This is intentional: an unattended register should not stay open under someone's name.

<Note>
  Locking does not delete anything. Sign back in and you find the register
  exactly as it was.
</Note>

## If the register can't find the main register

The roster is served by your store's main register. If the screen shows **Connecting to the main register…** or **Can't reach the main register**:

1. Check that the main register is powered on, with the NowOS app in the foreground.
2. Check that both devices are on the same Wi-Fi network.
3. In most cases the register finds the main register again on its own. If not, the **Find my main register** panel lets you scan again (**Rescan**) and pick the main register from the list.

To understand the connection states, see [connectivity](/en/pos/connectivity) and [the main register](/en/pos/main-register).
