Password Security Tips
- • Use a password manager to store unique passwords
- • Enable multi-factor authentication (MFA) everywhere
- • Never reuse passwords across accounts
- • Consider passphrases: "correct-horse-battery-staple"
Password Security Best Practices
Use Passphrases
A passphrase like "correct-horse-battery-staple" is stronger and easier to remember than "P@ssw0rd123". The ACSC recommends 14+ characters.
Unique for Each Account
Never reuse passwords. If one account is compromised, attackers will try those credentials everywhere.
Use a Password Manager
Password managers generate and store unique passwords for every account. You only need to remember one master password.
Enable MFA Everywhere
Multi-factor authentication adds a second layer of security. Even if your password is stolen, attackers can't access your account.
Avoid Personal Information
Don't use birthdays, names, or other personal details. Attackers can easily find this information on social media.
Check for Breaches
Use services like Have I Been Pwned to check if your email or passwords have appeared in data breaches.
Australian Cyber Security Centre Guidelines
The ACSC recommends the following password practices for Australian businesses and individuals:
Key Recommendations
- Use passphrases of 14 characters or more
- Avoid using single dictionary words
- Don't use predictable patterns (e.g., "Password1", "Qwerty123")
- Implement multi-factor authentication (MFA)
- Use a reputable password manager
- Never share passwords via email or messaging
- Change passwords immediately if a breach is suspected

Frequently Asked Questions
What makes a password strong?
A strong password has: minimum 14 characters (ACSC recommends 14+), mix of uppercase, lowercase, numbers, and symbols, no dictionary words or personal info, and is unique for each account. Passphrases like "correct-horse-battery-staple" are often stronger and easier to remember than complex short passwords.
How long would it take to crack my password?
Password crack time depends on length, complexity, and attacker resources. A 6-character password can be cracked in seconds. An 8-character complex password might take hours to days. A 14-character passphrase could take millions of years. Our tool provides realistic estimates based on current computing power.
Should I use a password manager?
Yes, password managers are strongly recommended by the ACSC and cybersecurity experts. They generate unique, complex passwords for every account, store them securely encrypted, and auto-fill login forms. This eliminates password reuse, the leading cause of account compromise.
