How BIP39 mnemonics work
The tool generates entropy from a cryptographically secure random source locally, appends the BIP39 checksum and maps it to the wordlist to produce 12/24 words; it can also validate a phrase. Fully offline, and the mnemonic is never uploaded.
Usage Guidelines & Tips
- A mnemonic equals your wallet private key: write it down offline and never screenshot, upload or share it.
- Prefer an offline environment; close the page when done, as the browser does not store the result.
