How to Enable or Disable Require Lowercase Letters for PIN in Windows 10


Windows Hello in Windows 10 enables users to sign in to their device using a PIN (Personal Identification Number). You can use this PIN to sign in to Windows, apps, and services.

One important difference between a password and a Hello PIN is that the PIN is tied to the specific device on which it was set up. That PIN is useless to anyone without that specific hardware. Someone who steals your password can sign in to your account from anywhere, but if they steal your PIN, they'd have to steal your physical device too!

Even you can't use that PIN anywhere except on that specific device. If you want to sign in on multiple devices, you have to set up Hello on each device.

You can block or require users to use digits, lowercase letters, uppercase letters, special characters in their PIN by enabling PIN Complexity Group Policy.

This tutorial will show you how to enable or disable PIN Complexity requirements for users to include at least one lowercase letter in their PIN in Windows 10.

You must be signed in as an administrator to be able to do the steps in this tutorial.

]If you set this Require lowercase letters policy to not configured (default), users are not able to include lowercase letters in their PIN by default. If require digits has been disabled or if require uppercase letters or require special characters has been enabled, then users may include lowercase letters in their PIN.

If you set this Require lowercase letters policy to enabled, users are required to include at least one lowercase letter in their PIN.

If you set this Require lowercase letters policy to disabled, users can't include lowercase letters in their PIN.

After you apply this policy, users will be required to change their PIN to meet the new PIN complexity requirements.
