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

Private Keys

Use private keys at brainwallet.org. Be careful - it can be easy to make mistakes if you don't know what you're doing.

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.
