Passwords & 2FA
Master password security and two-factor authentication
Why Passwords Matter
Your password is the key to your digital life - email, social media, bank accounts, and more. A weak password is like leaving your front door unlocked!
Common Password Mistakes:
- Too Short: Passwords under 12 characters are easily cracked
- Predictable: Using names, birthdays, or common words like "password123"
- Reused: Using the same password everywhere - one breach = all accounts compromised
- No Variety: Missing uppercase, numbers, or special characters

💡 Tips for Strong Passwords:
- Use at least 12-16 characters (longer is better!)
- Mix uppercase, lowercase, numbers, and symbols
- Avoid dictionary words and personal information
- Use unique passwords for each account
- Consider a passphrase: "Coffee$Morning!2025@Wildcat"
Two-Factor Authentication (2FA)
2FA adds an extra layer of security. Even if someone steals your password, they can't access your account without the second factor - usually a code from your phone!
🚨 HIGH PRIORITY: Secure Your Money!
Enable 2FA IMMEDIATELY on these accounts:
- 🏦 Banking & Credit Cards: Your actual money is at risk!
- 💳 PayPal, Venmo, Cash App: Payment apps are prime targets
- 🛒 Amazon, eBay, Shopping Sites: Stored payment methods can be stolen
- 📧 Email (Gmail, Outlook): Used to reset ALL other passwords
- ☁️ Apple ID / Google Account: Controls your entire digital life
⚠️ If someone hacks these accounts without 2FA, they can drain your bank account, make fraudulent purchases, or steal your identity. 2FA makes this nearly impossible!
How 2FA Works:
- You log in with your username and password (something you know)
- The service sends a code to your phone or authenticator app (something you have)
- You enter that code to complete login
- Access granted! Now attackers need BOTH your password AND your phone

📖 Real-World Example:
Without 2FA: Sarah's Amazon password was leaked in a data breach. A hacker used it to log in and spent $2,000 on gift cards before she noticed. The damage was done.
With 2FA: When the hacker tried to log in with the stolen password, Amazon asked for a code from Sarah's phone. The hacker didn't have her phone, so they couldn't get in. Sarah's account stayed secure!
💡 The lesson: 2FA stops hackers even when they have your password!
🔐 Authenticator App
In real life, codes refresh automatically every 30 seconds. This prevents hackers from reusing old codes!
Types of 2FA
- SMS Codes: Text message to your phone (convenient but less secure)
- Authenticator Apps: Google Authenticator, Authy, Microsoft Authenticator (more secure)
- Hardware Keys: Physical USB devices like YubiKey (most secure)
- Biometrics: Fingerprint or face recognition (convenient on mobile)
Password Managers
Can't remember unique 16-character passwords for every site? That's what password managers are for!
Benefits:
- Stores all passwords encrypted with one master password
- Generates strong random passwords automatically
- Auto-fills login forms securely
- Works across all your devices
- Popular options: 1Password, LastPass, Bitwarden, Dashlane
Remember: Your master password for the password manager needs to be REALLY strong - it's the key to everything!
