Trying to log into your Windows 10 computer you get the message: You’ve entered an incorrect PIN several times. To try again, enter A1B2C3 below – and that’s still not logging you in, right?
The reason behind this is varied although a common denominator around July/August 2021 relates to a Microsoft software update.
To log in successfully: Follow the instruction of entering A1B2C3. At the next screen look for ‘Sign-in options’.
Click the ‘Login’ option (next to the icon that shows the dots), sign in with your Microsoft account.
It would pay to reset/change the PIN for your computer. At least for now you’re likely logged back into your computer.
