# First-time setup

**What you'll do:** Sign in, set your device PIN, and save your User Recovery Key so the app is ready and recoverable.

**Why it matters:** Your User Recovery Key is the *only* way to restore your account on a new device. Getting setup right now prevents permanent data loss later.

**Steps**

1. Install **Oten Drive** (macOS: open the `.dmg`; iOS: install from TestFlight) and open it.
2. **Sign in** with your Oten account in the login window (Oten IDP).
3. **Create a device PIN** and re-enter it to confirm. This unlocks the app on this device only.
4. On the **Recovery Key** screen, **copy** your User Recovery Key and store it somewhere safe. You can't continue until you save it.
5. Wait a moment while your encrypted environment is created. You'll land on **My Drive**, ready to use.

**Common mistakes**

* **Not actually saving the Recovery Key.** Continuing without storing it durably. Put it in a password manager or a physical safe.
* **Saving the Recovery Key only on the same device.** If that device is lost, so is the key. Keep a second copy elsewhere.
* **Assuming the PIN protects your data.** It only gates the app on this device. Your recovery keys are what protect access to your files.
