Memorable Password Generator

Pronounceable passwords, with the entropy that pronounceability actually costs.

Syllables — 4

How this works

Each syllable is built as an onset, a vowel and a closing consonant — the onset drawn from twenty single consonants or twenty-three common clusters, the vowel from five, the coda from twenty. Those alphabet sizes are the entropy, and they are small, which is the honest point of the tool: the result is easy to say and type precisely because the generator is not choosing freely. Both figures are shown side by side — the real entropy from the generator's own choices, and the inflated figure you get by multiplying the length by a 26-letter alphabet as though every position were free.

What the results mean

Entropy
The real figure, from the generator's alphabet at each position.
A character count would claim
The overstatement. Shown so the gap is visible rather than argued about.
Syllables
More syllables means more entropy and a longer password, roughly 11 bits each.
Capitalise
Adds no entropy at all. It is a fixed rule, not a random choice.

Common problems and fixes

This is weaker than I expected
That is the trade, and it is why both numbers are shown. If you do not need to say the password aloud, a random one or a passphrase is strictly better.
I want something memorable and strong
Use the passphrase generator. Four words from a published list beat this comfortably and are easier to recall than syllables.
Can I make it stronger?
Add syllables. Each one is worth about eleven bits, which is far more than adding a digit or a symbol on the end.

Frequently asked questions

How is this different from a passphrase generator?

A passphrase picks whole words from a published list; this builds nonsense syllables. Passphrases carry more entropy per unit of memorability, so they are the better choice unless you specifically need one sayable token.

Why does capitalising add nothing?

Because it always capitalises the same position under the same rule. Entropy comes from choices an attacker cannot predict, and a fixed rule is not one.

Is a pronounceable password good enough?

At five or six syllables, yes for most purposes. At three it is not, and the number on the page tells you which side of that you are on.
