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 steet address, keyboard mashing, or anything you think is random, because chances are overwhelming that it isn't random enough for the needs of this tool.
The random mnemonic generator on this page uses a cryptographically secure random number generator, and 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 will not generate random mnemonics.
You can use this tool without having to be online.
