Security and Privacy
Security is a cornerstone of MetaMask® Extension®. The extension never stores private keys on external servers; instead, keys remain encrypted locally on your device. This design ensures that even if the MetaMask® servers were compromised, your assets would remain secure.
Additional security measures include:
- Two-factor authentication support for added account protection.
- Regular updates to patch vulnerabilities and improve encryption.
- Phishing detection alerts when interacting with potentially malicious websites.
- Clear permissions for dApps to access wallet information, giving users control over what is shared.
Users are encouraged to follow best practices, such as not sharing their seed phrase, using hardware wallets for large funds, and being cautious when interacting with unknown dApps.
Practical Usage Tips
To maximize the MetaMask® experience, consider the following tips:
- Regularly back up your wallet and seed phrase in secure locations.

These strategies help users maintain a smooth and secure experience while exploring the evolving Web3 ecosystem.
