Why secure access matters
MetaMask is a wallet and gatekeeper for Web3: whenever you “unlock” MetaMask or connect it to a dApp you are allowing that site to view and ask you to sign transactions. Secure access prevents theft of funds, accidental approvals, and exposure of private keys. Treat your wallet like cash — plan for both prevention and recovery.
Checklist for safe access
- Install MetaMask from official sources and verify extension signatures where possible.
- Use strong local passwords to lock the extension and enable OS-level security on the device.
- Never paste your seed phrase into a website or share it; seed = control of funds.
Connecting to dApps safely
When a site requests a connection, confirm why it needs access and what permissions it requests (viewing addresses vs. transaction signing). Revoke connections for dApps you no longer use and avoid granting blanket approvals to smart contracts.
Important: MetaMask or official support will never ask for your seed phrase or private key. Any page or person requesting it is malicious.
