I was seeing live youtube video of Aaron St. Hilaire just now and that guy unknowingly shared his myetherwallet private key to thousand of people live and within minute all his token was stolen from his account
I am new and just want to know ,we login to myetherwallet using password and private key .If a hacker see the private key ,how without password he can login to his myetherwallet address and stole all tokens
While accessing the wallet using private key, you wouldn't require to enter password, your wallet gets open with all functions as soon as you put peivate key on myetherwallet.com.
As am extra factor, if you wish to access the wallet using key-store file, the password becomes necessary, your wallet keys are encrypted in file, without passwprd it is impossible to decrypt them
