Strength of this formatStrong • 42 bits of entropy
A 4-word random passphrase has roughly 44 bits of entropy. 5 words pushes it to 55. That is stronger than most 10-character random passwords — and far easier to type and remember.
Why passphrases beat "P@ssw0rd1"
Short complex passwords are guessed faster than long simple ones. Computers crack by trying combinations — every extra word multiplies the time by hundreds of millions. A 4-word phrase from a 500-word list is over 60 trillion combinations. Most short "complex" passwords are under 1 trillion.
Quick Tips
- 1Never reuse the same passphrase across different sites.
- 2Store passphrases in a password manager (Bitwarden, 1Password, Apple Passwords). They sync to your devices and autofill safely.
- 3Add 2-factor authentication anywhere it's offered — even the strongest password helps less than a second factor.
- 4If you must remember by hand, write the phrase in a small notebook stored at home — never as a plain note on your phone.
- 5Change a passphrase right away if the site reports a breach.
