Mnemonic

You can enter an existing BIP39 mnemonic, or generate a new random one. Typing your own twelve words will probably not work how you expect, since the words require a particular structure (the last word is a checksum).

- For more info see the - BIP39 spec. -

- Generate a random mnemonic: - - - words, or enter your own below. - -

- Warning -

- Entropy is an advanced feature. Your mnemonic may be insecure if this feature is used incorrectly. - Read more -

Entropy

- Entropy values should not include the BIP39 checksum. This is automatically added by the tool. -

- - Entropy values must be sourced from a - strong source of randomness. - - This means flipping a fair coin, rolling a fair dice, noise measurements etc. - - Do NOT use phrases from books, lyrics from songs, your birthday or street address, - keyboard mashing, or anything you think is random, because chances are overwhelming it isn't - random enough for the needs of this tool. - -

- Do not store entropy. -

- Storing entropy (such as keeping a deck of cards in a specific shuffled order) is unreliable compared to storing a mnemonic. - Instead of storing entropy, store the mnemonic generated from the entropy. - Steganography may be beneficial when storing the mnemonic. -

- - The random mnemonic generator on this page uses a - cryptographically secure random number generator. - - The built in random generator can generally be trusted more than your own intuition about randomness. - If cryptographic randomness isn't available in your browser, this page will show a warning and the generate button will not work. - In that case you might choose to use your own source of entropy. -

- You are not a good source of entropy. -
