#CryptoSecurity101 Crypto Security 101: The Basics
1. Use a Hardware Wallet
What: Physical devices like Ledger or Trezor.
Why: Keeps your private keys offline and safe from online hacks.
2. Enable Two-Factor Authentication (2FA)
Use authenticator apps like Google Authenticator or Authy—not SMS—for securing accounts (exchanges, wallets).
3. Never Share Your Seed Phrase
Your seed phrase (12 or 24 words) = access to your crypto.
Write it down and store it offline in multiple secure locations.
NEVER store it in cloud services, notes apps, or email.
4. Beware of Phishing Attacks
Double-check URLs before logging into wallets or exchanges.
Don’t click links from unknown emails, Discords, or Telegram DMs.
Bookmark official sites.
5. Use a Secure Password Manager
Strong, unique passwords for every account.
Store them securely using a reputable password manager.
6. Keep Software Up to Date
Regularly update wallet apps, browsers, and your OS.
Updates fix security vulnerabilities.
7. Verify Transactions
Always double-check wallet addresses.
Use a small test transaction if unsure.
