Why passphrases beat complicated passwords
For years we were all told to make passwords "complex" — a capital letter here, a number there, a symbol on the end. The trouble is that humans are predictable. We turn password into P@ssw0rd!, and attackers' tools already know every one of those tricks. The result is a password that's hard for you to remember but easy for a computer to guess.
Passphrases flip that on its head. By stringing together several random everyday words, you create something with enormous length. And length is what truly matters, because every extra character multiplies the number of possibilities an attacker has to try.
The simple version: a four-word passphrase from our list has more than a trillion-trillion possible combinations. A typical "complex" eight-character password has far fewer — and people reuse those across sites, which makes things worse.
What the strength meter is telling you
The meter shows an estimate in bits of entropy — a measure of how unpredictable your passphrase is. Higher is better. As a friendly guide:
- Weak (under 40 bits) — fine for a throwaway login, not for anything that matters.
- Fair (40–59 bits) — okay for low-risk accounts.
- Strong (60–79 bits) — great for most everyday accounts.
- Very strong (80+ bits) — ideal for email, banking and your password manager.
Want more strength? Add a word. It's the single biggest lever you have, and it barely affects how memorable the phrase is.
A few friendly tips
- Use a unique passphrase per important account. Reusing one password everywhere is the most common way people get hurt.
- Let a password manager carry the load. Memorise a strong passphrase for the manager and your email; let the manager remember the rest.
- Turn on two-factor authentication wherever you can. It's a second lock on the door.
