Set Up Your MetaMask Account
Once MetaMask is installed, click the MetaMask icon (usually located in the upper-right corner of your browser) to open the extension.
Click the "Get Started" button.
You'll be prompted to create a new password. Make sure it's secure and that you can remember it, as you'll need it to log in.
After setting your password, click "Create."
MetaMask will then provide you with a "Secret Backup Phrase" (also known as a mnemonic phrase). This phrase is crucial for recovering your account if you ever lose access to it. Write it down and keep it in a secure place. Do not share it with anyone.
Confirm your Secret Backup Phrase by selecting the words in the correct order.
Once your backup phrase is confirmed, your MetaMask login is set up. Click "All Done."
