Accidentally locked my laptop from my Microsoft Account. How to unlock the device

Hi

Welcome to Microsoft community.

If you've accidentally locked your laptop via your Microsoft account and you're not seeing an "Unlock" option, here are the steps to unlock your device:

1. Physical Access: Go to your locked laptop. You'll need physical access to your laptop to unlock it.
   
2. Login Screen: At the login screen, you'll need to enter the password for the Microsoft account that the laptop is linked to. If you have changed your Microsoft account password recently, ensure you're using the latest one.
   
3. Reset Password: If you have forgotten your password, you can reset it. From the sign-in screen on your laptop, select 'I forgot my password' and follow the prompts. You'll need to verify your identity and then you can enter a new password.
   
4. Two-step Verification: If you have two-step verification activated, you'll need to provide an additional security code which can be sent to your email, phone number or authenticator app.
   

After successfully entering your password (and second verification step if applicable), your laptop should be unlocked.

The lock option from Microsoft account is for temporary scenarios where you've left your device unattended and you want to make sure no one else can access it. Once you unlock it from the device itself, it should be back to normal use.

Please feel free to let me know if you have any further updates, thanks.

I accidentally locked my Laptop

I accidentally locked my laptop through find device, when I use my PIN I can’t get into it, and when I use a system reset whilst keeping files it’s still locked, should I use a full system reset with deleting everything? It’s a HP Pavilion
