You will need a YubiKey to set up your Windows device. If you didn't receive one, contact mission-control@squareup.com before proceeding.
Your device must be connected to the internet to continue setup. If you have a VPN running on your network, turn it off — active VPN connections will prevent your laptop from completing enrollment.
Initial Setup
Press the power button, then select the country you reside in and choose your keyboard layout.

Connect your device to a wireless network (your home WiFi or Block-Guest) with internet access. The computer will check for updates and may reboot.
Enroll your device
You should see a screen with the Square or Block logo. Enter your @squareup.com or @block.xyz email address into the Microsoft login page.
Do not proceed. Contact mission-control@squareup.com for assistance.

You'll be taken to an Okta login page. Enter your username (e.g. if your email is johndoe@block.xyz, enter johndoe) and the password from your welcome email.


After entering your credentials, you'll be asked to verify your identity. You'll see two options — select Security Key or Biometric Authenticator.
You must use the Security Key or Biometric Authenticator option. Okta FastPass will not work at this stage.
A "Choose a passkey" screen will appear with two options — iPhone, iPad, or Android device and Security key. Select Security key, then insert your YubiKey when prompted.
Since this is a new YubiKey, you'll be prompted to create a PIN. Enter a 4-digit number as your PIN, then confirm it. You'll use this PIN each time you authenticate with your YubiKey. Once set, tap the YubiKey when prompted to complete verification.
You should now see a "Setting up for Work or School" screen. Let the computer complete this process — it may take several minutes and restart on its own. Eventually, a Windows login screen will appear showing "Other user." Enter your work email address and Okta password to sign in.




The "Setting up for Work or School" screen will return. An Okta login window will then appear — enter your username and password once more, then verify with your YubiKey when prompted.

Set up Windows Hello & PIN
When prompted, press OK to begin Windows Hello setup. Depending on your laptop, you can set up fingerprint or facial recognition. It's recommended to enable biometrics as it will be used for Okta FastPass later.

Create a PIN that is at least 8 characters long. You can include letters by checking the box. This PIN will be used to log into your computer — it's recommended to match your Okta password for consistency.

Click OK on the next screen to be taken to the Windows desktop.

You're signed in and on the desktop. Let's continue with updates and app setup.
