How to Create a New MetaMask Wallet

If you are new and don’t already have a crypto wallet:

Choose to start a new wallet instead of importing an existing one.

2. Set a Strong Password

Create a secure password that protects your wallet on your device.

MetaMask will show you a 12-word Secret Recovery Phrase.
This phrase is the master key to your entire wallet.

Important:

  • Write it down and store it in a safe offline place.

  • Never share it with anyone.

  • Do not store it in emails, screenshots, or cloud storage.

Always confirm the URL before connecting MetaMask.

3. Use a Strong Password

Avoid simple or reused passwords.

4. Lock Your Wallet When Not in Use

Click the account icon and select Lock.
