Memorable Passphrase Generator
Use this free memorable passphrase generator to make strong passwords from random words — easy to remember, hard to guess.
Your passphrase is made in your browser and never sent or saved anywhere.
Your passphrase:
The symbol, when ticked, is one of these 10 symbols: ! @ # $ % & * ? +
How to use this memorable passphrase generator
Step 1: Choose how many words you want. Four words is the default, and it is a good place to start. You can pick anything from 3 to 6 words.
Step 2: Pick a separator — a hyphen, a space, an underscore or a dot. The separator goes between the words and makes the passphrase easier to read and type.
Step 3: Tick the extras if you need them. Add a number if a site asks for a digit, add a symbol if a site asks for one, and tick capitalise first letters if you want each word to start with a capital. Then press Generate passphrase, and use Copy to copy it.
Worked example: a 4-word passphrase with hyphens
Take 4 words, a hyphen separator, and no extras. The generator picks four words at random from its built-in list — for example, river, table, honest and bright — and joins them with hyphens to give river-table-honest-bright. That is the whole passphrase: four ordinary words, easy to picture and easy to type, with no strange characters to remember.
Each word comes from a list of 2,048 common words, so each word adds about 11 bits of strength. Four words works out to about 44 bits, which is a good start. If you tick the number box, a digit is added at the end; if you tick the symbol box, one symbol is added at the end.
Why random words beat “P@ssw0rd!”
A password like P@ssw0rd! looks strong because it has a capital letter, a symbol and a digit, but it is still short, and it is a well-known pattern. Short passwords are quick to guess, however fancy they look, and swapping letters for symbols does not fix that. Length and randomness are what make a password strong.
Random words give you both. Four random words are far longer than most passwords people type, and because the words are picked at random, an attacker cannot guess them by trying common phrases. At the same time, ordinary words are easy to remember: you can picture a river, a table, something honest and something bright, and the passphrase stays in your head far better than a jumble of letters and symbols.
Entropy in plain words
Entropy is measured in bits, and bits are a measure of how many guesses an attacker would need. More words means far more guesses: every extra word multiplies the number of possible passphrases.
Each word comes from a 2,048-word list, and 2,048 is 2 to the power of 11, so each word adds 11 bits. That gives 3 words = 33 bits, 4 words = 44 bits, 5 words = 55 bits and 6 words = 66 bits. Adding a digit (0–9) adds about 3 bits, and adding one symbol from a set of 10 adds about 3 bits.
4 words is a good start — about 44 bits. Use 5 or 6 words for important accounts.
Privacy: nothing leaves your browser
Your passphrase is made in your browser and never sent or saved anywhere. The words are picked by your own device, the passphrase is shown only to you, and this site does not store it. Only you see it, so write it down somewhere safe or keep it in a password manager — if you lose it, nobody can get it back for you.
Frequently asked questions
What is a passphrase?
A passphrase is a password made of several random words, such as river-table-honest-bright. It is long, so it is hard to guess, and because it is made of ordinary words, it is easy to remember.
Why are word passphrases strong?
Because they are long and random. Each word is picked at random from a list of 2,048 words, so every extra word multiplies the number of possible passphrases. A short password with symbols swapped in is still short — length and randomness are what matter.
How many words should I use?
4 words is a good start — about 44 bits. Use 5 or 6 words for important accounts.
Is my passphrase sent anywhere?
No — it is made in your browser and never leaves your device. Nothing is sent to this site or saved anywhere.
Can I use it for my bank?
Yes for most sites, but check the site's password rules — some require a number or a symbol, so tick those boxes. A few sites also limit password length, so a 6-word passphrase may be too long for them.
