About Password Security

A password is a secret combination of letters, numbers, and symbols that grants access to accounts while preventing unauthorized entry. In today’s digital world, almost everyone uses passwords for different online accounts. Thus, knowing how to create strong passwords and safeguard them is crucial for maintaining online security.

Password strength

Password strength measures how resistant a password is against guessing or brute-force attacks. It primarily depends on factors like length, complexity, and unpredictability. Passwords that contain personal information (such as names, birthdays, etc.) are generally easier to guess and are considered weak. In addition to strong passwords, implementing security controls like two-factor authentication and account lockout policies further enhances protection against breaches.

Beyond creating a strong password, implementing proper security measures is crucial to minimizing the risk of a security breach. Security controls are safeguards designed to detect, prevent, or reduce potential threats. Examples include enabling two-factor authentication (2FA) and automatically locking accounts after multiple failed login attempts, both of which significantly strengthen account protection.

How to create a secure password

Follow these essential rules to build a strong and secure password: Include lowercase letters [a-z] Include uppercase letters [A-Z] Add numbers [0-9] Use special characters [!@#$%^&*()] Avoid using personal information Avoid common passwords (like “password”, “123456”, “qwerty”) Exclude company names or abbreviations Avoid predictable formats such as birthdates, license plates, or phone numbers Aim for a password that is at least 12 characters long The longer and more diverse the password, the stronger it becomes. Our Random Password Generator also offers the option to exclude ambiguous characters (like “I”, “l”, “1”) to prevent confusion while reading or typing passwords:

• Include lower-case letter(s) [a-z]
• Include upper-case letter(s) [A-Z]
• Include numbers [0-9]
• Include symbols [!@#$%^&*()…]
• Exclude words involving the user’s personal information
• Exclude words found in a password blacklist – there are password blacklists that can be found on the Internet, or it is possible that a company / other institution may have their own password blacklists
• Exclude company/institution name, as well as abbreviations of the name
• Exclude passwords that match common formats such as calendar dates, license plate numbers, phone numbers, or other common number formats

Many password policies recommend setting a minimum password length because longer passwords combined with a wide variety of character types — such as uppercase letters, lowercase letters, numbers, and special symbols — greatly increase overall password strength and security. A strong password is essential to protect accounts from hacking attempts and brute-force attacks.

The Random Password Generator on this website offers users the ability to exclude ambiguous characters for enhanced clarity and security. Characters like “L,” “I,” and the number “1” can often look similar on screens, leading to confusion when entering passwords. By eliminating these easily misread characters, users can avoid mistakes that might otherwise lock them out of their accounts. However, it’s important to note that excluding certain characters can slightly reduce the overall strength and complexity of the generated password.

Password entropy

Password entropy measures the randomness and unpredictability of a password, expressed in bits. Higher entropy means a password is harder to crack. For example, a password with 100 bits of entropy would require 2¹⁰⁰ attempts to exhaust all possibilities. On average, about half the possibilities must be tried before successfully guessing it through brute-force methods. A long, complex, and random password ensures maximum protection.

How to protect your password

Creating a strong password is just the first step — protecting it is equally important. Here are some best practices: Never share your password with anyone. Use different passwords for different accounts. Change your passwords regularly to limit risk. Avoid saving passwords on public or shared devices. Don’t keep obvious lists of your passwords, whether physical or digital. Use a reliable password manager to safely store and organize your passwords. Access sensitive accounts only on secure networks. Using a trusted password manager can help you create, manage, and retrieve strong passwords easily while keeping them safe:

• Don’t share your password with other people – Ideally, the user should be the only person who knows their password. For example, even if you trust the person that you share your password with, and even if that person has no malicious intent, they may be less careful about safeguarding your password than you would be. The more people who know your password, the more potential for your information to be stolen by someone else.
• Don’t use the same password across different websites and accounts – Although it may be more convenient to use the same password across different websites and accounts, it is not advisable. Having the same password for all your accounts, no matter how strong the password, may mean that a security breach on any single account compromises the safety of all of your accounts. Using a password manager can help you manage your passwords and accounts, and increase safety by allowing you to more easily use different passwords for different accounts. There are a number of different password managers that you can explore to find one that best suits your needs.
• Change your passwords regularly – This is another measure you can take that is also inconvenient, but theoretically, can help with keeping your accounts secure. This helps in cases where someone may know your password, and may access them, but may not immediately try to do something harmful. In these cases, changing your password would limit the period of time over which they have access to your account, assuming that they cannot determine the new password. In cases where you have saved your password on an old device you may have sold or thrown away, changing your password would disable a person from using a saved password.
• Never save your passwords to public devices – Ideally, try not to save passwords at all to reduce the risk of people gaining unwanted access to your accounts. In a similar vein, be careful of accessing sensitive accounts on unsecured public networks.
• Don’t keep obvious lists of your passwords that someone may be able to access, physical, or electronic – For example, a sticky note on your desk with accounts and their passwords, a word document on your desktop named “passwords” that contains information for all your accounts, or a note on your cellphone could open you up to unnecessary risk of password loss. As mentioned above, consider using a password manager instead. Phones, notebooks, etc., can be lost or stolen. Ideally, a person should use a password manager or be able to remember their passwords for various accounts based on the specific account.
