Use Pin on Boot

How do I use my PIN instead of my password after booting my computer?

Edit; If it makes a difference, I chose the “I prefer Google” option.

You can use the PIN to unlock the screen, while you have to use the password to sign in.

I know how to unlock from sleep mode with my pin. The question is: How do I unlock from boot with my pin?

For security reasons, you can’t use PIN to sign in.

My real goal is not to use my pin, per sy. But to not have to enter my Google password every time I boot FydeOS. I found a way to do that: I’m useing a local account now.
