Hello,Natalie Ann Datu
Thank you for posting in the Microsoft community.
Using a cell phone to unlock a laptop's password is usually impossible, and the process of unlocking a laptop's password involves several security mechanisms, primarily to protect the user's personal information and data security. Laptops use passwords as a form of authentication to ensure that only authorized users can access the system. So you can access the system only after entering the correct password and you cannot use your phone to remove the password from the computer.
Are you specifically trying to fulfill a need or function so you need to use your phone to remove your computer's PIN to use your laptop? If so, you can talk to me about the difficulty you're having and I'll come back and help you figure it out.
Have a nice day!
