I forgot my MyEtherWallet password. I don't see "forgot password" in MyEtherWallet website. Is this means that I can't change my password anymore? Anyone have suggestions about this matter? Kindly share it to me please. Thanks!
Actually you don't need any password in MyEtherWallet website. A password which you typed when created a wallet was used only once as a random phrase for creating a pair of address+private key. After that you should remember only these 2 things: ETH address and private key. You don't need anything else. At any time you can get access to this your address by the private key, either on MEW website or on any other website(or app, software,etc.) which supports ETH wallets.
Did you mean 'private key' when said 'password' (may be)? In this case your wallet is lost forever, nobody can restore the private key. Just stop to send ETH&tokens to that address and create a new one.
