If you sign in to Windows with a Microsoft account, you need to use a password. Your password helps keep your account secure, no matter what PC you sign in to or what apps, settings, and services you use while you're signed in.
If you don't want to enter your password every time you sign in, you can create other sign-in options to use with your account, like a picture password or a PIN. If your PC has a fingerprint scanner, you can also sign in with a fingerprint. (Whichever sign-in option you choose, you still need a "regular" password in place to use a Microsoft account.)
Swipe in from the right edge of the screen, and then tap Search.(If you're using a mouse, point to the lower-right corner of the screen, move the mouse pointer up, and then click Search.)
Enter sign, and then tap or click Change sign-in options.
Choose the sign-in option you'd like to use, and then follow the instructions.
You can also change password policy so that you don't need to enter your password each time you wake the PC from sleep. On the Sign-in options page, under Password policy, tap or click Change, and follow the instructions.
If your PC is on a domain, some sign-in options, like smart cards or picture password, might be managed by your system administrator.
If you sign in to Windows with a local account, you can choose not to enter a password. However, we don't recommend this—it's the least secure way to sign in to your PC. You can also switch a Microsoft account to a local account, but you can't use a local account to download apps from the Windows Store or sync settings online.
Swipe in from the right edge of the screen, tap Settings, and then tap Change PC settings.(If you're using a mouse, point to the lower-right corner of the screen, move the mouse pointer up, click Settings, and then click Change PC settings.)
Tap or click Accounts, and then tap or click Your account.
Tap or click Disconnect, and then follow the instructions.
If you're using a local account with a password, you can delete the password to sign in without one, but we don't recommend it.
Enter sign, and then tap or click Sign-in options.
Under Password, tap or click Change.
Verify the current password for your local account.
Leave the New password, Reenter password, and Password hint fields blank, tap or click Next, and then tap or click Finish.
Now, you (or anyone) can sign in to your local account and use your PC without a password.
