How to Secure Your Crypto Wallet

Protecting your crypto wallet is essential to safeguarding your digital assets. Follow these best practices to keep your FxWallet secure.

1. Back Up Your Mnemonic Phrase Immediately​

Your mnemonic phrase is the master key to your wallet. If you lose it, you permanently lose access to your assets.

  • Write it down on paper — never store it digitally.
  • Store the paper backup in a secure, fireproof location.
  • Consider using a metal backup for long-term protection.
  • Never take a screenshot or photo of your mnemonic phrase.

2. Enable Biometric Authentication​

FxWallet supports fingerprint and Face ID authentication. Enable biometrics to prevent unauthorized access if your device is lost or stolen.

3. Set a Strong PIN​

Use a unique 6-digit PIN for FxWallet. Avoid obvious combinations like 123456 or your birthday.

4. Never Share Your Private Key or Mnemonic​

  • FxWallet will never ask for your mnemonic phrase or private key.
  • No legitimate support agent will ever request your private key.
  • Anyone who asks for your mnemonic phrase is attempting to steal your assets.

5. Only Download FxWallet from Official Sources​

  • Download FxWallet only from the official website or official app stores.
  • Verify the developer name before installing.
  • Beware of fake apps with similar names or icons.

6. Be Cautious with DApp Connections​

  • Only connect your wallet to trusted DApps.
  • Review token approval permissions carefully before confirming.
  • Revoke unnecessary approvals regularly using tools like Etherscan Token Approvals.

7. Keep Your App Updated​

Always use the latest version of FxWallet to benefit from the latest security patches and improvements.

Remember: In a self-custody wallet, you are fully responsible for your assets. FxWallet cannot recover lost mnemonics or reverse unauthorized transactions.
