Password Security Criteria

Understanding what makes a password strong and secure

Strong Password Characteristics

Length (12+ characters)

Longer passwords exponentially increase security

Character Diversity

Mix of uppercase, lowercase, numbers, and symbols

Unpredictability

Avoid common words, patterns, and personal information

Uniqueness

Use different passwords for different accounts

No Repetition

Avoid repeating characters or sequences

Regular Updates

Change passwords periodically, especially after breaches

Common Password Weaknesses

Dictionary Words

Common words are easily cracked by dictionary attacks

Personal Information

Birthdays, names, and addresses are easily guessed

Simple Patterns

Sequences like '123456' or 'qwerty' are predictable

Short Length

Passwords under 8 characters are vulnerable

Single Character Type

Only letters or only numbers reduce complexity

Password Reuse

Same password across multiple accounts increases risk
