Forgot my computer password or I'm locked out
Being locked out is stressful, but there are official ways back in, so let's start with the simple checks.
Be careful: Resetting a computer to get in can erase everything on it. Only reset a computer that belongs to you, and if you see a BitLocker screen, find your recovery key by signing in to your own Microsoft account on another device.
What to do
Step 1: Check that Caps Lock is off. On a Chromebook, it's Search + Alt (or Launcher + Alt).
Step 2: Your Chromebook password is your Google Account password. If you changed it recently, use the new one.
Step 3: If you forgot it, use another device to go to the Google sign-in page, choose Forgot password? and follow the steps.
Step 4: Once reset, sign in to the Chromebook with the new password. It needs Wi-Fi the first time.
Still stuck? Contact Microsoft or Apple support through their official website or app, or take the computer and proof you own it to a trusted repair shop.
