How it works

Select each position independently from the tool's original fixed word list.
Apply the chosen case and separator without changing the selected word identities.
Optionally append an independently generated two-digit suffix and report the word-list size.

Worked example

Eight lower-case words with hyphens could produce meadow-lantern-copper-river-orbit-sparrow-quartz-garden, representing 64 bits from word choices before any optional suffix.

Limits and interpretation

Each phrase contains 8–16 words and each batch contains at most 50 phrases.
The bundled list has exactly 256 equally eligible words, so each independent word contributes 8 bits and the default eight-word phrase has 64 bits from word choices.
Some systems reject spaces or long values; check the destination's password rules.

Privacy

Your inputs and generated results stay in this browser. This tool does not put them in a URL, analytics event, server log, or external request.
