What is a passphrase?
A passphrase is a password made of several random words, such as Orbit-Candle-River-Plum-Stage. Because each word is picked at random from a long list, a passphrase can be as strong as a complex password while being far easier to remember and type.
How strong is a passphrase?
Words are drawn from a list of 7,776 words, so each one adds about 12.9 bits of entropy.
- 4 words — about 52 bits: fine for low-risk accounts.
- 5 words — about 65 bits: good for most accounts.
- 6 words or more — 77+ bits: recommended for password managers and email.
The words must be chosen at random. A sentence or quote you picked yourself is far weaker, because attackers try common phrases first.
Separators, capitals and numbers
Separators make a passphrase easier to read and type. Capital letters and an added number help meet password rules that require them, but add little strength — an extra word is worth much more.

Frequently asked questions
How many words should a passphrase have?
At least five for everyday accounts and six or more for your most important ones.
Is a passphrase stronger than a password?
A six-word passphrase (about 77 bits) is roughly as strong as a random 12-character password with all character types.
Can I use spaces between the words?
Most services accept spaces, but some do not. Hyphens or dots are the safest choice.
