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
Valid entropy values include:
+ 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 are not a good source of entropy. +
