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"

Security Best Practices

🔤

Use Passphrases

A passphrase like "correct-horse-battery-staple" is stronger and easier to remember than "P@ssw0rd123".

🔐

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.

Common 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.
