Windows 10 supports creating a password-free account for a local user account, although it is always recommended to use password-protected user accounts. You can not create a password-free account for a Microsoft account. However, Windows 10 can be configured to log in automatically without entering a password, refer to How to automatically login to Windows 10.
If you already have a password for the account, please refer to the How to turn off the password on Windows 10 guide. Important note: If you often carry a laptop or tablet, you must set a strong password and encrypt the hard drive.
Use the instructions given below to create a local user account without a password in Windows 10.
Option 1: Create a local account without a password when the network is connected
Step 1: On a Windows 10 computer, go to Settings > Accounts > Family and other users.
Step 2: In the “Other users” section, click the “Add someone else to this PC” option. This will open the account creation dialog.
Step 3: Here, click the “I do not have this person’s login information” link.
Step 4: In the dialog box that appears, click the link to add a user without a Microsoft account.
Step 5: Now, enter the desired name for the user account, then enter nothing in the password, and then re-enter the password field.
Step 6: Click the Next button to create an account.
Option 2: Set up a local account without a password when the network is disconnected
Step 1: Turn off Wi-Fi on your computer or disable Ethernet temporarily.
Step 2: Go to the Settings > Accounts > Family and Other Users, and then click the “Add Someone else to This PC” option.
Windows 10 provides you with a local user account instead of pushing you to create a Microsoft account when you are offline.
Step 3: Enter the user account name to be used for the new local account. To create an account without a password, you need to keep the password and then re-enter the password field to be blank. Finally, click the “Next” button to create an account without a password.
