3 Secure Your Recovery Phrase

This is the most critical security step for your extension wallet:

  • Complete verification by selecting words in correct order
  • Consider metal backup for fire/water protection

Frequently Asked Questions

Is the Coinbase Wallet Extension different from the mobile app?

While both provide access to the same self-custody wallet features, the extension is optimized for browser-based dApp interactions on desktop, while the mobile app is designed for smartphone use. They can both access the same wallet accounts using your recovery phrase, but the extension provides seamless integration with desktop browsing and tab-based workflows.

Can I use the extension on multiple browsers or computers?

Yes, you can install the Coinbase Wallet Extension on multiple browsers and computers. Each installation will be separate, but you can import your wallet to each using your recovery phrase. Many users install it on their primary work computer, home computer, and different browsers for flexibility. All installations will have access to the same accounts and funds.

What happens if I uninstall the extension or clear browser data?

If you uninstall the extension or clear browser data, you'll need to reinstall the Coinbase Wallet Extension and restore your wallet using your recovery phrase. Your funds remain safe on the blockchain - only your local access is affected. This is why physical storage of your recovery phrase is absolutely critical for recovery.

How do I update the Coinbase Wallet Extension?

The extension updates automatically through your browser's extension system. Browsers check for updates regularly and install them silently in the background. You can manually check for updates by going to your browser's extensions page (chrome://extensions/ for Chrome, about:addons for Firefox) and looking for update options. Manual updates are rarely needed as browsers handle this automatically.

Can I connect a hardware wallet to the extension?

Yes, the Coinbase Wallet Extension supports hardware wallet connections. You can connect popular hardware wallets like Ledger and Trezor to the extension for enhanced security. This allows you to sign transactions using your hardware device while still enjoying the convenience of the browser extension interface. The private keys remain secured on your hardware device.

What should I do if the extension stops working or shows errors?

If the extension stops working properly, try these steps: First, restart your browser completely. If that doesn't work, go to your browser's extensions page and toggle the extension off and on. Clear your browser cache and cookies. As a last resort, uninstall and reinstall the extension (you can restore your wallet with your recovery phrase). Also ensure your browser is updated to the latest version.
