- Store it digitally (no photos, cloud storage, etc.)
- Enter it on any website, even if it looks legitimate
Recognizing Scams
Common threats to Coinbase Extension users:
- Fake browser extensions mimicking Coinbase Wallet
- Phishing emails pretending to be from Coinbase

- Fake token approvals that drain your wallet
