Complexity
Combine uppercase, lowercase, numbers, and symbols for maximum security.
Avoid Common Patterns
Don't use dictionary words, sequences (1234), or personal information.
Unique Passwords
Never reuse passwords across different accounts or services.
Password Managers
Consider using a password manager to generate and store strong passwords.
Regular Updates
Change passwords periodically, especially for critical accounts.
