Security Best Practices

While MetaMask provides a secure environment for managing your cryptocurrencies, users must follow these security practices:

  • Never share your seed phrase or private keys with anyone
  • Store your seed phrase offline in a secure location
  • Use a strong, unique password for your MetaMask wallet
  • Always verify website URLs before connecting your wallet
  • Double-check transaction details before confirming
  • Keep your browser and MetaMask extension updated
  • Consider using a hardware wallet for large holdings

Remember: MetaMask will never ask for your seed phrase. Any request for your seed phrase is a scam.
