Even without deep computer knowledge, you can understand the importance of securing your computer. One way to do this is by enabling Secure Sign-in, which requires users to press Ctrl + Alt + Delete on the lock screen before logging in. It adds an extra step but protects the system from login imitating programs attempting to gather password information. This article will guide you on how to turn on or off Secure Sign-in in Windows 10.

Method 1: Toggle Secure Sign-in using netplwiz
Step 1: Press the Windows + R key combination, type 'netplwiz' in the Run dialog, and then press Enter.

Step 2: A User Account window will appear. Navigate to the Advanced tab and check the box next to Require users to press Ctrl+Alt+Delete to enable Secure Sign-in (uncheck to disable). Then, click Apply > OK.

Method 2: Toggle Secure Sign-in in Local Security Policy
* Note: This method is not applicable in Windows 10 Home version as it lacks Local Security Policy.
Step 1: Press the Windows + R key combination, type 'secpol.msc' in the Run dialog, and then press Enter.

Step 2: In the Local Security Policy window, on the left-hand panel, expand Local Policies, and click on Security Options. On the right-hand side, double-click on the entry Interactive logon: Do not require CTRL+ALT+DEL.

Step 3: A new window will appear. Choose Disabled to enable Secure Sign-in (or select Enabled to disable), then click Apply > OK.

Method 3: Toggle Secure Sign-in using Registry Editor
* Note: Registry Editor is a recommended editor for those with computer knowledge. To ensure system safety, make a Registry backup before editing, allowing restoration in case of errors during the process.
Step 1: Press the Windows + R key combination, in the Run dialog, type 'regedit' and press Enter.

Step 2: On the left-hand panel, navigate to HKEY_LOCAL_MACHINE > SOFTWARE > Microsoft > Windows NT > CurrentVersion > Winlogon. On the right-hand side, double-click on the entry DisableCAD.

* If DisableCAD is not found, create it by right-clicking in the right-hand panel, selecting New > DWORD (32-bit) Value, and naming it DisableCAD.

Step 3: Adjust the Value data to 0 to enable Secure Sign-in (or set it to 1 to disable), then click OK.

On the next startup of Windows 10, you will encounter the protective Secure Sign-in before logging in.
