Why this matters
Weak and reused passwords are behind a large share of account takeovers. When one website is breached, criminals try the same email and password on banking, email and Microsoft 365. A long, unique password for every important account stops this from spreading.
What you'll need
- The account you want to protect
- Optional: a password manager
Step-by-step instructions
Step 1
Use a passphrase instead of a short password
Length matters more than complexity. Combine four or more random, unrelated words into a phrase. The Australian Cyber Security Centre recommends passphrases of at least 14 characters.
- Good example style: "purple kettle harbour violin"
- Avoid song lyrics, quotes or personal details
Step 2
Make it unique to each account
Never reuse a password for your email, banking or work accounts. Your email password is the most important, because it can be used to reset everything else.
Step 3
Avoid predictable patterns
Attackers try common substitutions and patterns first.
- Names, birthdays, pets, sporting teams or suburbs
- "Password1!", "Summer2026" or keyboard runs like "qwerty"
- Adding a number to the end of an old password
Step 4
Store it in a password manager
A password manager (such as Bitwarden, 1Password or the one built into your browser) can generate and remember a unique password for every site. You only need to remember one strong passphrase to unlock it.
Step 5
Turn on multi-factor authentication
Even a strong password can be stolen by phishing. Multi-factor authentication (MFA) adds a second check, such as an app approval, so a stolen password alone is not enough.
Frequently asked questions
How long should a password be?
Aim for at least 14 characters. A passphrase of four or more random words is long, strong and easier to remember than a short complex password.
Should I change my passwords regularly?
Only change a password if you suspect it has been exposed. Forcing frequent changes tends to produce weaker, predictable passwords.
Summary
A long, unique passphrase stored in a password manager and backed by MFA puts you well ahead of most attackers.
