Frequently Asked Questions

1. Is MetaMask® Extension safe?

Yes, when downloaded from official sources. Your keys are encrypted and stored locally in your browser. However, browser extensions are potentially vulnerable to malware, so maintain good computer security practices.

Yes, but you'll need to install the extension separately on each browser and either create new wallets or import existing ones using your recovery phrase.

3. What happens if I uninstall the extension?

Your wallet remains on the blockchain, but you'll need your recovery phrase to restore access. Always back up your recovery phrase before uninstalling.

4. How do I update MetaMask® Extension?

Extensions typically update automatically. You can manually check for updates in your browser's extension manager.

The extension is for desktop browsers only. For mobile, download the official MetaMask® mobile app.
