2FA (Two-Factor Authentication) adds an extra layer of security to accounts by requiring:
1. Something you know (password or PIN)
2. Something you have (code sent via SMS, email, or authenticator app)
This makes it harder for unauthorized users to access accounts, even if they have the password.
Types of 2FA:
1. SMS-based: Codes sent via text message
2. Authenticator app: Apps like Google Authenticator or Authy generate time-based codes
3. Hardware token: Physical devices generating codes
4. Biometric: Fingerprint, facial recognition, or voice recognition
Benefits:
1. Improved security: Reduces risk of unauthorized access
2. Protection against phishing: 2FA makes phishing attacks less effective
3. Compliance: Some regulations require 2FA for sensitive data
Best practices:
1. Use authenticator apps: More secure than SMS-based 2FA
2. Enable 2FA: On all accounts that support it
3. Use strong passwords: Combine 2FA with strong, unique passwords
To avoid regrets in crypto journey, always use 2FA to protect your funds in all exchange.
All exchange have 2FA functionality.
See you next time.
