MetaMask Extension Security Tips

Wallet security is essential when managing cryptocurrency. Keep your Secret Recovery Phrase private and store it securely offline. Never share it with anyone, including people claiming to be customer support representatives. Use a strong password, keep your browser updated, and review wallet connection requests carefully. Remember that connecting a wallet does not automatically make a website trustworthy. Avoid suspicious links, unknown token approvals, and unexpected transaction requests.
