Keeping your crypto wallet secure starts with protecting your private keys and recovery backup, keeping your device locked and updated, and checking every transfer or signing request. Regular checks of connected apps and token permissions help you remove access you no longer need. The right protections depend on how you hold your crypto: a self-custody wallet puts you in charge of its keys, while an exchange account also needs a secure login and multi-factor authentication. Read the full guide below to check your setup.

Start With a Wallet Security Checklist

Open your wallet and work through these six checks:

1. Check your recovery backup: Confirm that you have the complete backup, can read it, and know where it is stored. Use your wallet’s supported backup check where available.
2. Lock and update your devices: Enable a screen lock, set a unique wallet app password where supported, and install official software and firmware updates.
3. Verify your wallet app: Check that you installed it through the provider’s official download links. Save the genuine support page instead of relying on search ads.
4. Check before signing: Verify the full recipient address, network, asset, amount, fee, and the action the wallet asks you to approve.
5. Remove old access: Review connected apps and account sessions. Check spending approvals separately; disconnecting an app may leave those permissions active.
6. Know your emergency response: A suspicious approval may need revocation. A leaked seed phrase or private key requires a new wallet with new recovery material.
