Two-Factor #Authentication (2FA) typically combines a password with a code, whereas Multi-Factor Authentication (MFA) adds more layers, such as biometrics (fingerprint/face) or hardware tokens. Read MFA vs 2FA: What's the difference https://windowspost.com/2fa-vs-mfa/

Key Differences Between 2FA and MFA

Number of Factors: 2FA limits authentication to two layers (e.g., password + OTP), while MFA can incorporate three or more (e.g., password + OTP + fingerprint).

Security Level: MFA generally provides superior security against sophisticated attacks because it relies on multiple independent factors.

Complexity & UX: 2FA offers a more streamlined user experience with fewer steps. MFA may cause more user friction due to additional login steps, but it enhances security.

Flexibility: MFA offers greater flexibility, allowing organizations to adopt adaptive, risk-based authentication, while 2FA is a fixed two-step process

2FA Example: Entering a password (knowledge) and a code texted to your phone (possession).

MFA Example: Entering a password, a code from an app, and using a biometric scan (fingerprint or face)

An OTP (One Time Password) is valid for exactly 30–60 seconds.
Even though no one stores it anywhere. So, how does the server verify it without ever saving it?

Well, that’s usually called a Time-based One-Time Password (TOTP).

Here’s how it actually works:

• A secret key is shared between your device and the server (only once)
• Both use the current time window (like 30 seconds)
• And a secure algorithm (HMAC)

Using these, both sides generate the same OTP independently.

✅ No storage
✅ No database lookup
✅ Just math + time

When you enter the OTP, the server simply regenerates it and checks:
👉 “Does this match?”

That’s how your OTP is verified… without ever being saved. 🔐

High CPU usage in Windows 11 usually means a process is using more CPU cycles than it should. It could be due to excessive background apps, pending Windows updates, corrupted system files, or high-resource processes like antivirus scans and indexers.

Fixes for High CPU Usage (Windows 11)

Restart Your PC: This is the quickest way to clear stuck processes and memory.

Use Task Manager: Press Ctrl + Shift + Esc, find processes with high CPU usage, right-click them, and select "End task".

Disable Startup Apps: In Task Manager, go to the "Startup apps" tab, right-click unnecessary apps, and select "Disable".

Update Windows & Drivers: Go to Settings > Windows Update to ensure you have the latest performance patches.

Check Power Settings: Search for "Choose a power plan" in the Control Panel, and select "Balanced" or "High Performance".

Scan for Malware: Run a full scan with Windows Defender, as viruses can cause high CPU usage.

Disable SysMain (Superfetch): Search for "Services," find "SysMain," right-click to stop it, which can reduce background resource usage.

Disable High Precision Event Timer: In Device Manager, find "High precision event timer" under System Devices, right-click, and disable it
