Length: Aim for a minimum of 12 characters. Longer passwords are generally more secure because they are harder to crack.

Complexity: Include a mix of uppercase letters, lowercase letters, numbers, and special characters (such as !, @, #, $, etc.). This increases the complexity and makes the password harder to guess.

Avoid Common Patterns: Don’t use easily guessable patterns like “123456”, “password”, “qwerty”, or sequential keyboard combinations (e.g., “asdfg”).

Avoid Personal Information: Don’t use easily obtainable information such as your name, birthday, or common words related to your hobbies or interests. (Creating Secure Passwords)

Unique Passwords: Use a unique password for each of your accounts. Reusing passwords across different sites increases your vulnerability—if one site is compromised, all your accounts using that password could be at risk.

Passphrases: Consider using a passphrase—a combination of random words strung together. For example, “correct horse battery staple” is easier to remember than a complex string of characters and offers strong security. (Creating Secure Passwords)

Password Managers: Use a reputable password manager to generate and store complex passwords securely. This way, you only need to remember one strong master password.

Two-Factor Authentication (2FA): Whenever possible, enable two-factor authentication. This adds an extra layer of security beyond just a password. 

Regular Updates: Periodically update your passwords, especially for sensitive accounts. This reduces the risk of long-term exposure in case a password is compromised.

Be Wary of Phishing: Always verify the source before entering your password. Phishing attacks often mimic legitimate websites to steal your login credentials.
