FAQs: Top User Concerns

Q1: Is my recovery phrase stored by Coinbase®?

No. Your 12-word phrase is generated and stored locally – Coinbase® has zero access.

Q2: Can I connect to Coinbase® exchange via the extension?

No. The extension is for non-custodial Wallet only. Use Coinbase.com for exchange services.

Q3: How to recover funds if I lose my phrase?

Impossible. The phrase is your only backup. Store it offline on steel plates.

Q4: Why won’t dApps detect my extension?

Fixes:
Update Chrome & extension
Disable conflicting extensions (e.g., other wallets)
Toggle "Prefer Coinbase® Wallet" in settings

Q5: Is Bluetooth pairing with mobile safe?

Yes – uses E2E encryption. For maximum security:
Disable when not in use
Confirm all transactions on mobile screen

Q6: How to revoke dApp permissions?

Go to Wallet Guard
Connect wallet
Select "Revoke Access"
