To recover your MyEtherWallet (MEW) account, you must use your private key, recovery phrase, or Keystore file. If you have these, visit the MEW website, select "Access My Wallet," and follow the prompts. These recovery details are necessary for access to be recovered, as MEW cannot restore accounts for security reasons. Always store your recovery information securely.
