MetaMask Extension Security Tips

Wallet security is essential when managing cryptocurrency online. Always download MetaMask through its official website or a verified browser extension store.

Never share your Secret Recovery Phrase or private keys with anyone. Avoid entering recovery information on unfamiliar websites, and be cautious of fake support agents, suspicious pop-ups, and fraudulent wallet downloads.

Before approving a transaction, carefully review the amount, recipient address, network, and requested permissions. Connecting to a decentralized application does not automatically make it trustworthy, so research unfamiliar services before using them.

Troubleshooting MetaMask Extension Problems

If MetaMask does not appear in your browser, open the browser's extension settings and check whether it is installed and enabled. You can also pin the extension to your toolbar for easier access.

If a decentralized application cannot connect, refresh the page, reopen MetaMask, and verify that you are using the correct blockchain network. Restarting your browser or updating the extension through the official store may also help resolve common issues.
