> Generate random-word passphrases in supported word lists.

[Open tool](https://www.toolcabana.com/zh/passphrase) · [生成器与营销](https://www.toolcabana.com/zh/category/generators-and-marketing)

Tool ID: passphrase. Requested language: zh. Description language: en. Complete guide translation: no; untranslated sections use English.

## Overview (en)

The passphrase generator strings together 3 to 24 random words drawn with cryptographic randomness from a BIP39 word list in English, Spanish, French, Italian, Portuguese, Japanese, Korean or Czech. You choose the separator, how many passphrases to create (up to 100) and whether to capitalize each word, and it reports the uniform entropy in bits.

## Supported tasks (en)

Draws independent words using cryptographic randomness from the selected BIP39 word list. These are password passphrases, not recovery seeds.

## Steps (en)

1. Enter the requested values in the settings panel.
2. Adjust the basic settings, then open Advanced mode for export and fine-tuning options. Custom settings stay active when the panel is closed.
3. Run passphrase generator, review the output, then use the available copy or download controls.

## Settings

- Words (en; key: words; type: number); minimum: 3; maximum: 24
- Count (en; key: count; type: number); minimum: 1; maximum: 100
- Separator (en; key: separator; type: text)
- Word-list language (en; key: language; type: select): English [en], Spanish [en], French [en], Italian [en], Portuguese [en], Japanese [en], Korean [en], Czech [en]
- Capitalize each word (en; key: capitalize; type: checkbox)

## Limitations (en)

Use finite numbers, valid dates and the ranges shown by each control. Invalid values produce an error without a downloadable result.

## Questions (en)

### How strong is an 8-word passphrase?

Each BIP39 word list has 2,048 words, so every word adds 11 bits. The default of 8 words gives 88 bits of uniform entropy, which the tool displays next to the word-list size. Adding words raises the figure by 11 bits each.

### Can I use this passphrase as a crypto wallet seed phrase?

No. Words are picked independently and no BIP39 checksum is added, so the output is a password passphrase, not a valid cryptocurrency recovery seed. Create seed phrases with your wallet's own software.

### Can I change the separator between passphrase words?

Yes. The default is a hyphen, but you can type any separator, such as a space, a period or a number. Capitalize each word is an advanced option that uppercases the first letter of every word using your locale's rules.

### What are the input limits?

Use finite numbers, valid dates and the ranges shown by each control. Invalid values produce an error without a downloadable result.
