# Initial Tutorial
> Screen-by-screen walkthrough of the wizard that appears the first time you plug your ZeroKeyUSB in. Orientation, keyboard layout and master PIN.
The first time you plug your ZeroKeyUSB into a USB-C port, a 9-page setup wizard starts automatically (in Spanish by default — the localized strings appear below). This guide walks you from the welcome screen to a device ready to store credentials.
***
## Step 1 — Welcome splash
When you plug the cable in, the screen lights up showing the logo for a couple of seconds. This confirms the device booted correctly and passed its firmware security check.
*Wait about 2 seconds. The wizard appears automatically — you don't have to press anything.*
***
## Step 2 — Page 1: Welcome
First page of the wizard. The inverted top bar shows the title and a page indicator `<1/9>`. The body briefly describes what the device is and what to do.
*Press **Right** to advance. If the body has more text than fits on screen, use **Up/Down** to scroll before continuing.*
***
## Step 3 — Page 2: Navigation
Explains what each of the 5 pads does. This is the only page that describes the controls explicitly.
*Read the page and press **Right** to move to the next one.*
***
## Step 4 — Page 3: Rotate screen
If the golden dots end up on your left instead of on the right, flip the device physically — or rotate the screen in software with **Center**. The orientation is saved on the device and persists across power cycles.
*Press **Center** to toggle the orientation (you will see `NORMAL ↔ ROTADA` on screen). When the controls feel right, press **Right** to continue.*
***
## Step 5 — Page 4: Keyboard layout
ZeroKeyUSB emulates a USB keyboard. So that passwords with special characters (`@`, `!`, `#`, etc.) type correctly on your computer, the device needs to know **your** keyboard layout.
*Press **Center** to cycle through EN-US, ES-ES, FR-FR, DE-DE, IT-IT, PT-PT, DA-DK, SV-SE, HU-HU. When yours appears, press **Right**.*
You can change this later from **Menu → Settings → Keyboard**.
***
## Step 6 — Page 5: Master PIN (introduction)
This page explains the PIN rules before asking for one. Pick between 4 and 16 digits (0–9). It is the only thing standing between an attacker and your credentials.
*Press **Center** to move on to the PIN entry screen.*
**There is no PIN recovery.** If you forget it, the only option is a factory reset that wipes **all** your credentials. Memorize the PIN — or write it down somewhere physically safe.
***
## Step 7 — Enter the PIN
The numpad screen. Each digit is entered with **Up/Down** (to choose 0–9) and **Right** (to confirm and advance to the next digit). The small arrows on the sides of the active digit remind you of the available moves.
*For each digit of your PIN: **Up/Down** to the correct number, then **Right** to confirm it. When you finish the last digit, the cursor jumps to the tick (✓) symbol. Press **Center** on the tick to save the PIN.*
To erase the last digit if you make a mistake, press **Left**.
***
## Step 8 — Page 6: PIN saved
After entering the PIN, the wizard shows it back to you **once** so you can memorize it. This is your last chance to see it in cleartext.
*Write the PIN down or memorize it. When you have it, press **Right**.*
***
## Step 9 — Page 7: Unlocking
Explains that from now on, every time you plug the USB in, you will have to enter the PIN. And that repeated failures trigger an exponential wait.
*Read the page and press **Right** to continue.*
**Exponential backoff:** first failure = 5 s wait, second = 10 s, third = 20 s… up to \~43 min max. The counter resets when you enter the correct PIN. Nothing is wiped automatically.
***
## Step 10 — Page 8: Accounts
A preview of the main screen — how credentials are navigated once you are unlocked.
*Press **Right**.*
***
## Step 11 — Page 9: All set
Last page. Reminds you that you can reach the main menu by pressing **Left** on the first credential (or **Right** on the last, going through "Add New" first).
*Press **Center** to exit the wizard and reach the PIN screen. That's it — the device is set up.*
***
## Step 12 — Ready to use
After pressing Center, the device takes you to the PIN numpad to enter the PIN you just created (the **same** one you will see every time you plug the device in from now on). When you enter the PIN correctly, you will reach the main screen — but since there are no credentials yet, the **Add New** screen appears directly.
*Press **Center** to create your first credential — or follow the dedicated guide at [Create your first credential](/getting-started/first-credential).*
