- Personal information leakage
- Financial losses

How to Create Strong Passwords
Length First
Password length is a key factor in security. It's recommended to have at least 12 characters, and the longer, the better.
Complexity
A good password should include:
- Uppercase letters (A-Z)
- Lowercase letters (a-z)
- Numbers (0-9)
- Special characters (!@#$%^&*)
Avoid Predictability
Don't use:
- Personal information (birthday, name, phone number)
- Common words
- Sequential keyboard characters
- Simple substitutions (like @ instead of a)
Passphrase Strategy
A good method is to use "passphrases" instead of passwords:
``
Bad: P@ssw0rd
Good: Coffee-Mountain-Sunrise-2024!
``
Passphrases are longer, easier to remember, and still very secure.
Multi-Factor Authentication
In addition to strong passwords, you should also enable multi-factor authentication (MFA):
- SMS verification codes
- Authenticator apps (like Google Authenticator)
- Hardware keys (like YubiKey)
Even if your password is leaked, attackers cannot access your account.
Password Management Strategies
Use Different Passwords for Each Account
Never use the same password on multiple websites. Once one website is breached, all accounts using the same password will be at risk.
Use a Password Manager
Remembering dozens of complex passwords is unrealistic. Using a password manager can:
- Generate random strong passwords
- Securely store all passwords
- Auto-fill login forms
- Sync across devices
Recommended password managers:
- 1Password
- Bitwarden
- LastPass
Regularly Update Passwords
You should change your password in the following situations:
- Website data breach occurs
- Suspected account compromise
- Password shared with others
- Haven't changed for a long time (recommended to change important account passwords annually)
