Strong security habits help protect both your personal and professional life.
🔑 How to Create Strong Passwords
Passwords remain the first line of defense for most online accounts.
Best Practices:
✅ Use at least 12–16 characters
✅ Include:
- Uppercase letters
- Lowercase letters
- Numbers
- Symbols
✅ Avoid:
- Birthdays
- Names
- Common words
- Reused passwords
Example:
❌ password123
❌ john1988
✅ T7#kL92!zW@4Pq
🔒 How to Use a Password Manager
Managing dozens of complex passwords manually is difficult.
Password managers help by:
- Generating strong passwords
- Storing credentials securely

📱 How to Enable Multi-Factor Authentication (MFA)
MFA adds an extra layer of protection beyond passwords.
With MFA, users must verify their identity using an additional factor such as:
- Authentication apps
- Security keys
- SMS codes
- Biometrics
Steps to Enable MFA:
- Log in to your account settings.
- Open Security Settings.
- Select Multi-Factor Authentication.
- Choose an authentication method.
- Save backup recovery codes.
MFA can stop many account takeover attempts even if a password is compromised.
