Free Password Generator

Creating a secure password becomes easier when you follow a set of rules that improve overall password security. This mainly includes building a strong password, updating it from time to time, and avoiding common passwords such as password, 123456, qwert, etc. Below are some important guidelines that can help you create a strong password:

• 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 – these lists exist online, and some companies or institutions also maintain their own password blacklists
• Exclude company/institution name or even short forms of the name
• Exclude passwords that follow common formats like calendar dates, license plate numbers, phone numbers, or familiar numerical sequences

Most password policies also require a minimum password length because longer passwords with more character variation are generally more secure.

The random password generator on this website also gives an option to exclude ambiguous characters. These include characters like "L" and "I" which may be hard to distinguish on a digital screen. For example, an upper-case "I" can look very similar to a lower-case "L" or even the number 1. Such confusion can sometimes lock the user out of their own account. However, excluding characters slightly reduces potential password strength.

The password generator also calculates password entropy, measured in bits. Higher entropy means the password is harder to guess. In brute force attacks (where every possible combination is tried), a password entropy of 100 bits means 2^100 possibilities would need to be checked. Typically, only half the combinations would need to be tried before the correct one is found.

How to protect your password

Creating a strong password is only the first step; protecting it is equally important. Below are some practices that can help you keep your password safe:

• Don not share your password with anyone. Even if you trust someone, they may not protect your password as carefully as you do. The more people who know your password, the greater the chance of unauthorized access.
• Do not use the same password on multiple websites or accounts. It may feel convenient, but if one account gets compromised, all your other accounts become vulnerable. Using a password manager makes it easier to create and manage multiple different passwords safely.
• Change your passwords regularly. It's inconvenient, but it can help stop someone who quietly knows your password from accessing your accounts for long periods. If you saved your password on an old device you no longer use, changing it ensures the old saved password becomes useless.
• Consider using a password manager to securely store and manage your passwords.
• Never save your passwords on public devices. Also avoid logging into sensitive accounts on unsecured public networks.
• Do not keep obvious lists of your passwords, whether written or digital. Avoid notes on your desk, phone notes, or documents named in an obvious way like "passwords". If needed, use a password manager instead. Devices can be lost or stolen, so memorising or securely storing passwords is safer.
