Password Security Guide
Why Password Security Matters
Every day, millions of passwords are compromised through data breaches, phishing attacks, and brute force attempts. A weak password can expose your personal information, financial accounts, and sensitive data to cybercriminals.
What Makes a Password Strong?
Length is King
The most important factor in password strength is length. Each additional character exponentially increases the time needed to crack your password.
- 8 characters: Minutes to hours
- 12 characters: Decades to centuries
- 16+ characters: Millions of years
Character Variety
Using different types of characters makes your password much harder to guess:
- Lowercase letters: a-z
- Uppercase letters: A-Z
- Numbers: 0-9
- Symbols: !@#$%^&*
Unpredictability
Avoid common patterns, dictionary words, and personal information that could be guessed or found on social media.
Strong vs Weak Password Examples
Weak Passwords (Never Use These!)
❌ john1985
❌ qwerty
❌ 123456789
❌ iloveyou
Why these are weak: They use common words, predictable patterns, or personal information that's easy to guess.
Strong Passwords
✅ Coffee&Mountain92!
✅ BlueSky#River345
✅ Dancing*Elephant$67
Why these are strong: They're long, use multiple character types, combine unrelated words, and include numbers and symbols.
Password Creation Strategies
1. The Passphrase Method
Create a memorable sentence and modify it:

2. Random Words Method
Combine 3-4 unrelated words with numbers and symbols:

3. First Letters Method
Take the first letter of each word in a memorable phrase:
↓
MdwbiLoM15t2020!
Common Password Mistakes to Avoid
- Using personal information: Names, birthdays, addresses, pet names
- Simple substitutions: Replacing 'a' with '@' in common words
- Keyboard patterns: qwerty, asdf, 123456
- Common words: password, admin, welcome
- Short passwords: Anything under 12 characters
- Reusing passwords: Using the same password across multiple accounts
Password Management Best Practices
1. Use Unique Passwords
Every account should have its own unique password. If one account is compromised, your other accounts remain safe.
2. Consider a Password Manager
3. Enable Two-Factor Authentication (2FA)
Add an extra layer of security by requiring a second form of verification, such as:
- SMS codes
- Authenticator apps
- Hardware security keys
4. Regular Password Updates
Change passwords immediately if:
- You suspect an account has been compromised
- A service reports a data breach
- You've shared the password with someone
- It's been over a year since you last changed it
Recognizing Security Threats
Phishing Attacks
Be wary of emails or websites asking for your password. Legitimate companies will never ask for passwords via email.
Data Breaches
Stay informed about breaches affecting services you use. Change passwords immediately if your data may have been compromised.
Social Engineering
Attackers may try to trick you into revealing passwords through phone calls or fake support requests.
Special Considerations
Work vs Personal Accounts
Use different passwords for work and personal accounts. Follow your company's password policy for business accounts.
Sharing Passwords
Avoid sharing passwords whenever possible. If you must share access, use proper account sharing features or change the password afterward.
Public Computers and Wi-Fi
Be extra cautious when entering passwords on public computers or unsecured Wi-Fi networks. Consider using a VPN for additional protection.
