FAQs
How often should I change my MetaMask password?
We recommend changing passwords every 3-6 months, especially if you've connected to new DApps.
Can I recover my account if I lose my private key?
Yes, but only if you've securely stored your 12-word seed phrase. This phrase can regenerate your private key.
Why can't I see my connected sites?
Ensure you're using MetaMask's latest version. Some older versions may not display this feature.
Is it safe to import accounts from other wallets?
Yes, but always verify you're using the official MetaMask application before entering sensitive data.
What's the difference between locking and logging out?
Locking temporarily disables access (password required), while logging out clears session data completely.
8. Final Recommendations
- Bookmark MetaMask's official website to avoid phishing scams
- Consider using a hardware wallet for large asset holdings
- Regularly review transaction histories for unauthorized activity
By mastering these account management techniques, you'll maintain optimal control over your Web3 experience while minimizing security risks. Remember that blockchain transactions are irreversible, making proactive account management crucial.
