Use Strong and Unique Passwords

Passwords are the first line of defense. Avoid using easy-to-guess passwords such as Birthdate, First name, “123456” or “password”

Tips for Creating Secure Passwords

Combine uppercase, lowercase letters, numbers, and symbols
Never reuse the same password for multiple accounts

Use a Password Manager

Apps like LastPass, 1Password, or Bitwarden can help you store passwords securely.

Enable Two-Factor Authentication (2FA)

Two-Factor Authentication adds an extra layer of security. Even if your password is hacked, the attacker still needs a verification code from your phone. Examples of Services with 2FA: Gmail, Facebook, Instagram, Online Banking

Use an Authentication App
