PIN sign-in option is considered much better as compared to password. If you’ve Windows Hello supported device, you can setup face recognition after you setup PIN.
PIN is usually stored on the device as compared to password, which is stored on server. So if someone cracked your password, he can get into the account. But if someone cracked your PIN, he can’t sign-in to account unless he have the actual device to which PIN is tied.
According to Microsoft, in Windows 10, PIN is backed by a Trusted Platform Module (TPM) chip, which is a secure crypto-processor that is designed to carry out cryptographic operations. So any changes in the TPM chip or if you’ve cleared TPM, the PIN associated with it might not work then.
Under this condition, when you use PIN to sign in to your device, you’ll have following message displayed:
Your PIN is no longer available due to a change in the security setting on this device. You can setup your PIN again by going to Settings > Account > Sign-in options.
