The most common passwords in 2026 are still "123456," "password," and first names. These crack in under a second. Here is what actually makes a password strong.
What Makes a Password Strong?
Three properties matter: length, randomness, and uniqueness.
- Length — Each extra character multiplies difficulty exponentially. 16 characters is the recommended minimum.
- Randomness — Names, dates, and keyboard walks are in every cracker dictionary. Machine-generated randomness is essential.
- Uniqueness — Reusing passwords means one breach exposes every account that shares it.
Password Entropy and Crack Times
- 8 chars, lowercase only: ~38 bits — crackable in hours
- 12 chars, mixed case + numbers: ~72 bits — years to crack
- 16 chars, full character set: ~105 bits — centuries to crack
- 20 chars, full character set: ~131 bits — longer than the age of the universe
How Passwords Are Cracked
- Dictionary attacks — Billions of known passwords tested in seconds.
- Brute force — Modern GPUs test billions of combinations per second.
- Credential stuffing — Leaked passwords from one breach used on other sites.
Passphrases: A Genuine Alternative to Random Strings
A string of several random, unrelated words — like "correct horse battery staple" — can match or exceed the entropy of a shorter random-character password while being genuinely easier for a human to type and remember when needed. Four random common words drawn from a dictionary of about 7,000 words gives roughly 51 bits of entropy, comparable to an 8-character fully random password, but a passphrase scales better: each additional word adds far more entropy than most people expect, and it stays memorable in a way a longer random string doesn't.
A Mistake That Undoes a Password Manager's Benefit
Using a password manager to generate unique passwords for every site is genuinely strong practice — but protecting that vault with a weak or reused master password creates a single point of failure that defeats the entire purpose. The master password is the one password you actually need to remember yourself, so it's worth making it a long, unique passphrase rather than something short enough to type quickly, since a compromised master password exposes every stored credential at once.
