Ok, you won't be able to use any of the Windows hello to reset it, but you need to create another admin to help you reset yours.
To do so,
Here are the steps:
- Type netplwiz in the search on the taskbar and hit enter. When launched, click on "Add". On the next window, click on the bottom where it says to create an account without Microsoft email. This will allow you to define your own username.
- When the above user is created, back to the main netplwiz page, double click on this new user, go to the Group Membership tab, make it administrator. Save the change.
- Restart the computer. Sign into new user. Then launch netplwiz again, and select your old local user and then click on reset password to reset it. When done, restart the computer, sign back into your old local user.
- Type sysdm.cpl in the search on the taskbar and hit enter, go to Advanced tab, click on the "Settings" button at the User Profile section. Then delete the user profile for the new local user you just created..
- Launch netplwiz again, delete the new local user from there.
