Is a passphrase really as safe as a random password?

A long passphrase of several truly random words can be very strong. The catch is randomness — predictable phrases, quotes, or personal details are much weaker.

Which passwords should I memorize?

Only a few: your device login, your email, and your password manager's master password. Let the manager store strong, random passwords for everything else.

How to Create a Strong Password You Can Actually Remember

The passphrase method makes passwords both strong and memorable. Learn how it works, why it beats complex short passwords, and when to use a generator.

The usual advice — "use a long, random mix of letters, numbers, and symbols" — creates passwords that are strong but impossible to remember. There's a better approach for the handful of passwords you truly need to memorize: the passphrase.

Why length wins

Password strength comes mainly from length, not from swapping a for @. A short "complex" password like P@ss1! is weak because attackers' software tries those predictable substitutions first. A longer string, even of ordinary words, has vastly more possible combinations and takes far longer to crack.

The passphrase method

Pick four or more random, unrelated words and string them together, for example: copper-lantern-drizzle-badger. It's long (great for strength), but because it tells a little mental picture, it's easy to remember. Add a number or symbol if a site requires it. The key word is random — don't use a famous quote or your pet's name and birthday, which attackers can guess.

Passphrase vs. generated password

Use a memorable passphrase for the few passwords you must type from memory: your device login, your password manager's master password, and your primary email.
Use a fully random generated password for everything else — since your password manager remembers those, they don't need to be memorable, just strong and unique.

The rules that matter most

Never reuse passwords. One leaked site shouldn't unlock the rest of your life.
Longer is stronger. Aim for 16+ characters or a 4+ word passphrase.
Use a password manager so each account can have a unique, random password.
Turn on two-factor authentication where you can — it protects you even if a password leaks.

Generate the strong ones instantly

For every account your password manager handles, create an uncrackable password with the free Password Generator. It uses your browser's cryptographic randomness and never sends anything over the internet.
