This updated article (originally published April 17, 2017) explains how to secure your Microsoft account, crucial given its connection to various Microsoft services and the sensitive data it holds. Protecting your account doesn't require expert knowledge; these steps will suffice.

Strengthen Your Account's Defenses

Choose a robust password: Longer passwords incorporating uppercase and lowercase letters, numbers, and symbols are harder to crack. Avoid common passwords or those easily linked to personal information. Crucially, use a unique password for your Microsoft account—don't reuse it elsewhere.

Enable two-step verification: This adds an extra layer of security. A code sent via text, email, or an authenticator app is required in addition to your password. Even if your password is compromised, access will be blocked without this second factor. Activate this under your Microsoft account's Security settings, then Advanced security options, and finally, Additional security.

Monitor Account Activity

Regularly review your account's activity: Your online Microsoft account displays recent purchases and active devices. Scrutinize these lists for unfamiliar entries. For suspicious activity, use Microsoft's unexpected charge troubleshooter before contacting support. Remove any unrecognized devices immediately.

Check your activity log: Under your account's Security settings, find "View my activity" for a detailed breakdown of account access times, devices, and locations. Report anything suspicious using the provided links to initiate a password change. Similar activity logs may be accessible within the operating systems of your linked devices (e.g., Windows 10 Settings > Accounts > Sign-in options).

Maintain Up-to-Date Software

Keep software updated: Regularly update your Windows operating system (Settings > Update & Security), browser, applications, and antivirus software. This is a fundamental security measure against vulnerabilities.

Avoid Phishing Scams

Be vigilant against scams: Never click unsolicited links or share your password via phone. Modern browsers often detect phishing websites. Report any calls claiming to be from Microsoft support offering virus removal; these are often attempts to install spyware.

Manage Your Privacy Settings

Control your privacy: Your online Microsoft account's Privacy settings allow you to review and delete collected data, including activity logs, location history, etc. While Microsoft collects data for various reasons (some beneficial, like location services), you have control over what's stored. Additional privacy controls are available within individual applications (like Edge) and the Windows 10 Settings app (Privacy).

By following these steps, you can significantly enhance the security and privacy of your Microsoft account.
