<h2>Summon Brain Wallet</h2>
|

<p>
|
||||
A brain wallet generates an <i>Ethereum</i> wallet from a username and a password
|
||||
without using any servers to store your information. If you lose your username
|
||||
or password, <b>no one</b> can help you recover them. Anyone who can guess your
|
||||
username and password can steal your funds. Brain wallets should <b>not</b> be
|
||||
considered a safe way to store large amounts of ether nor for long periods of time.
