A private key is a alphanumeric string that gives its owner access to cryptocurrency funds. It should be kept secret at all times because whoever has access to it can spend the associated funds. MyEtherWallet (MEW) is a free, open-source platform that allows you to generate a new ethereum web wallet(イーサリアムウェブ財布) or access your existing one. In order to do this, you need your private key. In this article, we will show you how to generate and use a private key on MEW.

How to Generate a New Private Key on MEW

1. Go to https://www.myetherwallet.com/#generate-wallet and select “Keystore / JSON File”.

2. Enter a strong password and click “Create New Wallet”. Make sure to remember this password as you will need it later to unlock your wallet.

3. Click “Download Keystore File (UTC / JSON)”. This will download a JSON file to your computer that contains your private key. Keep this file in a safe place as it cannot be recovered if lost. The next time you want to access your wallet, you will need this file and the password you used to encrypt it.

4. To view your private key, click “I understand. Continue.” and then “Add Wallet”. Select “Keystore / JSON File” and upload the JSON file you just downloaded.
