Common Password Mistakes

❌ Top Password Weaknesses:

Using Personal Information
- Names, birthdays, addresses
- Easy for attackers to guess or research
Dictionary Words
- "password", "admin", "login"
- Vulnerable to dictionary attacks
Simple Patterns
- "123456", "qwerty", "abcdef"
- Easily guessed by automated tools
Reusing Passwords
- Same password for multiple accounts
- One breach compromises all accounts
Predictable Substitutions
- "Password" → "P@ssw0rd"
- Still vulnerable to smart attacks

Password Generation Strategies

Method 1: Passphrase

Concept: String of random words Example: "correct horse battery staple" Pros: Easy to remember, naturally long Cons: May not meet symbol requirements

Enhanced Passphrase: "Correct-Horse-Battery-Staple-2024!"

Method 2: First Letter Method

Concept: Take first letters of a memorable sentence Sentence: "My favorite movie is The Matrix from 1999!" Password: "MfmiTMf1999!" Enhancement: Add symbols and vary capitalization

Method 3: Random Generation

Concept: Truly random characters Example: "mK9$pL2#nR7@qW5!" Pros: Maximum security Cons: Requires password manager

Method 4: Pattern with Variation

Base Pattern: Service + Unique Element + Date + Symbol Example for Gmail: "Gmail&MySecret&2024!" Variation: Change elements for each service

Remember

A strong password is like a good lock - it doesn't guarantee security, but it makes the attacker's job much harder. Combined with other security practices like 2FA and staying alert to phishing, strong passwords form the foundation of good cybersecurity hygiene.

The best password is one you don't have to remember - let your password manager handle the complexity while you focus on protecting your master password and backup codes.
