1. Use an Automated Password Manager A password manager is an automated program that stores and encrypts user passwords so they can easily be accessed and used without having to remember them manually. 2. Use a Unique Password for Each Account A unique password should be used for each and every account in Windows 10. Using the same password for multiple accounts makes them vulnerable to hacks. 3. Use Two-Factor Authentication Two-factor authentication adds an extra layer of security to your accounts by requiring a second form of authentication, usually via a mobile app or a text message, prior to allowing access to your account. 4. Use Longer and Complex Passwords Using longer and complex passwords is the best way to protect your accounts from attacks. Long and complex passwords are harder to guess and harder to brute-force. 5. Regularly Change Your Passwords It’s a good idea to regularly change your passwords in order to ensure maximum safety. This will help to prevent against any attempts to guess or brute-force your passwords.
