Create strong passphrases you can actually remember
Long beats complicated. A passphrase of several unrelated words is both stronger and easier to remember than a short tangle of symbols. The Australian Cyber Security Centre (cyber.gov.au) recommends this approach.
- Choose four or more random, unrelated words, such as a phrase no one would guess from knowing you.
- Aim for length: longer passphrases are far harder to crack than short complex ones.
- Avoid anything guessable — pet names, birthdays, your footy team, or song lyrics.
- Use a different passphrase for each important account, so one leak does not unlock the others.
- Let a password manager generate and store random passphrases for accounts you rarely type by hand.
- Keep your email and password-manager passphrases the strongest of all, since they protect everything else.
Still stuck after those?
You’ve done the right thing by trying. Send whedo.it a quick note — what you tried, what you saw — and a senior pair of eyes will be on it the same business day.
