What is Two-Factor Authentication?
Two-Factor Authentication (2FA) adds a second layer of security beyond your password. Even if someone steals your password, they can't access your account without the second factor — something only you have.
Think of it like a bank vault: you need both your key (password) AND your fingerprint (second factor) to get in.
Types of 2FA
1. SMS Text Messages
A code is sent to your phone via text message. Not recommended — vulnerable to SIM swapping attacks where attackers convince your carrier to transfer your number.
2. TOTP Authenticator Apps (Recommended)
Time-based One-Time Password apps generate 6-digit codes that change every 30 seconds. Apps like SecureVault's built-in authenticator, Google Authenticator, and Authy use this method. This is the most practical and secure option for most people.
3. Hardware Security Keys
Physical USB or NFC devices like YubiKeys. Extremely secure but requires carrying a physical device. Best for high-value accounts.
4. Biometric
Fingerprint, face recognition, or iris scanning. Convenient but not universally available for web accounts.
Why TOTP is the Best Choice
- No cellular service needed — Works offline, unlike SMS
- Can't be SIM-swapped — Codes are generated on your device
- Free — No special hardware required
- Universal — Supported by virtually every major service
Setting Up 2FA with SecureVault
SecureVault is uniquely powerful because it serves as both your password manager and your TOTP authenticator. Here's how to set it up:
- Log in to your SecureVault dashboard
- Navigate to Security Dashboard
- Click "Enable 2FA"
- Scan the QR code with any authenticator app
- Enter the 6-digit verification code
- Save your backup codes in a safe location
You can also use SecureVault to store TOTP codes for other services — Google, GitHub, AWS, and more — all in one place.
Which Accounts Should Have 2FA?
- Email — Your email is the master key to all other accounts (password resets go here)
- Banking & Financial — Obvious high-value targets
- Social Media — Account takeovers can damage reputation
- Cloud Storage — Google Drive, Dropbox, iCloud
- Developer accounts — GitHub, AWS, hosting providers
- Password Manager — Protect the keys to the kingdom
Common 2FA Mistakes to Avoid
- Using SMS for 2FA on high-value accounts
- Not saving backup codes
- Using the same TOTP device as your password storage (SecureVault solves this with integrated management)
- Disabling 2FA because it seems inconvenient
