How to Enable Screen Lock / Passcode on Windows 10

Set up a PIN, password, or biometric lock to protect your device.

Last verified: February 21, 2026

Windows screen lock security combines two separate layers: the authentication method (PIN, password, Windows Hello face or fingerprint) configured in Settings > Accounts > Sign-in Options, and the screen lock timing configured in Settings > System > Power & Sleep and the Screen Saver (password on resume) setting. Windows Hello PIN is recommended over passwords for everyday use because it's device-local — unlike a Microsoft account password, the PIN never leaves the device and cannot be phished. Windows 11 also introduces Enhanced Phishing Protection which warns you if you type your Windows password into a non-Microsoft app or webpage.

Quick Steps

Follow in order for the fastest result.

  1. 1Go to Settings > Accounts > Sign-in options. Add a PIN (recommended) or a Password. Optionally set up Windows Hello face or fingerprint unlock.
  2. 2Set screen lock to activate after 30 seconds to 1 minute of inactivity for security without interruption.
  3. 3Biometric unlock (fingerprint, face) is the recommended default — PIN or password always remains as the backup.

Frequently Asked Questions

What is the most secure screen lock type for Windows 10?
A strong alphanumeric password is the most secure option, but modern biometrics (Face ID on iPhone, fingerprint on Android) provide strong security with far better usability. A 6-digit PIN is a reasonable minimum. Avoid 4-digit PINs, patterns, and swipe-only locks for any device with sensitive data.
How do I set up fingerprint unlock on Windows 10?
Go to Settings > Accounts > Sign-in options > Fingerprint recognition (Windows Hello) and click Set up. Follow the prompts to scan your finger. You need a PIN set up first as a backup.
How long should my Windows 10 wait before locking?
30 seconds to 1 minute is the recommended balance between security and convenience for most users. Very short intervals (15 seconds) are appropriate for high-security environments. Setting it to Never is only appropriate for a desktop in a physically secure, private location.
What happens if I forget my Windows 10 screen lock PIN or password?
If using a Microsoft account, reset the PIN from the lock screen by clicking I forgot my PIN. If using a local account with no recovery options, you'll need to use Windows Recovery Environment to reset it.
