How Do I Keep My Web3 Wallet Secure?

fomoJanuary 22, 2026

Security is paramount when managing your own crypto assets. With fomo, you don't have to worry about your seed phrase, because you can recover your wallet by signing in with your email or Apple ID, which makes it more secure over a Web3 wallet. Here are the essential practices to keep your Web3 wallet safe.

Protecting Your Private Keys

Your seed phrase and private keys should never be stored digitally in plain text. Avoid:

• Screenshots
• Cloud storage (iCloud, Google Drive, Dropbox)
• Email
• Notes apps
• Text messages

Physical paper backups in secure locations (safe deposit boxes, fireproof safes) remain the gold standard. Consider storing copies in multiple secure locations.

Recognizing Scams and Phishing

Be skeptical of:

• Unsolicited messages about your wallet or crypto
• Unexpected airdrops requiring you to connect your wallet
• Links sent via DM on social media or Discord

Always verify URLs before connecting your wallet. Legitimate projects will never ask for your seed phrase. When in doubt, don't connect.

Hardware Wallets for Large Holdings

If you hold substantial value in cryptocurrency, consider a hardware wallet (like Ledger or Trezor) for cold storage. Keep only what you need for regular transactions in hot wallets (browser extensions and mobile apps).

This limits your exposure if a hot wallet is compromised.

Regular Security Audits

Periodically review your wallet's connected sites and revoke permissions you no longer use. Tools like Revoke.cash help manage and remove token approvals that could pose risks.

Additional Security Tips

• Use unique passwords for any wallet-related accounts
• Enable 2FA (two-factor authentication) wherever available
• Keep your software updated to patch security vulnerabilities
• Use a dedicated device for high-value transactions if possible
• Be careful on public WiFi - avoid making transactions on unsecured networks

Security Made Simpler

Managing security can feel overwhelming, especially for newcomers. Platforms like fomo help by:

• Handling complex key management behind the scenes
• Flagging potentially malicious tokens with warnings
• Providing a controlled environment that reduces exposure to scam dApps

You get the benefits of self-custody without dealing with the technical complexities that often lead to security mistakes.
