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!
There is no password.
When you created wallet on Myetherwallet you got your keys, you probably save them to your PC.
Because you have used them at least once to check your balance?
So the question you must ask yourself did you ever opened your wallet after initial creation, if not there is a good chance that you never downloaded your keys in the first place.
