Windows 10: Incorrect PIN

My surface pro laptop has the following message on the sign in page "you've entered an incorrect PIN several times. To try again, enter A1B2C3 below" when I do this it asks for the PIN and then says it is incorrect. This is a continuousnous loop.with apparently no other way to sign in. What can I do?.

Log-in Pin is incorrect after Anniversary update


I had the same issue after my update on Windows 10. I knew that my pin hadn't changed but it was saying it was incorrect. So I said that I forgot my pin and it started going through the steps to reset the pin entered my regular password and when the window popped up to set a new pin I said cancel and then I chose the option to set my pin later. I exited the screen, logged off logged back in, and set up a new pin which happened to be the same pin I had before and it worked. If this still doesn't work I can show step by step screen shots if you need. I have a surface 3 with Windows 10 fully updated 10.0.14393.0

 

Log-in Pin is incorrect after Anniversary update


After the Windows 10 Anniversary update, when I try to sign in with my pin, it says the pin I entered is incorrect.
I know it is the correct pin number. It's the same pin I've used since installing Windows 10.
I have to sign in using my password. I want to go back to using my pin, but I can't change the pin, since don't know what it thinks my old pin is. I understand others are having the same problem.

Any suggestions would be appreciated.
