| <h3 className='mt-6 fw-medium'>About this tool</h3> | ||
| <p> | ||
| This tool generates cryptographically secure random passwords | ||
| and strings. You can choose the length of the password and | ||
| select the characters you want to include in the generated | ||
| password: lowercase letters, uppercase letters, numbers, and | ||
| symbols. | ||
| </p> | ||
| <p> | ||
| This tool uses the browser's built-in{' '} | ||
| <code>crypto.getRandomValues</code> function to generate random | ||
| numbers. This function is available in most modern browsers. It | ||
| will fall back to <code>Math.random</code> if the function is | ||
| not available. | ||
| </p> | ||
| <h3 className='mt-6 fw-medium'> Why use a password generator?</h3> | ||
| <p> | ||
| Passwords generated by this tool are more secure than passwords | ||
| that are easy to remember. They are also more secure than | ||
| passwords that are easy to guess or that are based on personal | ||
| information. | ||
| </p> | ||
| <p> | ||
| Using a password generator can help you create strong passwords | ||
| that are difficult to crack. This can help protect your online | ||
| accounts from being hacked or compromised. | ||
| </p> | ||
| <h3 className='mt-6 fw-medium'> | ||
| Best practices for using passwords | ||
| </h3> | ||
| <p> | ||
| Here are some best practices for using passwords generated by | ||
| this tool: | ||
| </p> | ||
| <ul> | ||
| <li> | ||
| <strong>Use a unique password for each account:</strong> Do | ||
| not reuse passwords across multiple accounts. If one account | ||
| is compromised, all accounts with the same password are at | ||
| risk. | ||
| </li> | ||
| <li> | ||
| <strong> Generate strong passwords:</strong> Use a password | ||
| generator to create strong, random passwords that are | ||
| difficult to guess. Strong passwords typically include a mix | ||
| of lowercase letters, uppercase letters, numbers, and symbols. | ||
| </li> | ||
| <li> | ||
| <strong>Generate long passwords:</strong> Longer passwords are | ||
| generally more secure than shorter passwords. Consider | ||
| generating passwords that are at least 15 characters long. | ||
| </li> | ||
| <li> | ||
| <strong>Use a password manager:</strong> Consider using a | ||
| password manager to store and manage your passwords securely. | ||
| A password manager can help you generate strong passwords, | ||
| store them securely, and autofill them when needed. | ||
| </li> | ||
| <li> | ||
| <strong>Enable two-factor authentication:</strong> Enable | ||
| two-factor authentication (2FA) on your accounts whenever | ||
| possible. 2FA adds an extra layer of security by requiring | ||
| users to provide two forms of identification to access their | ||
| accounts. | ||
| </li> | ||
| </ul> | ||
| <h3 className='mt-6 fw-medium'> | ||
| Is it safe to use a password generator and this tool? | ||
| </h3> | ||
| <p> | ||
| This tool generates passwords and strings directly in your | ||
| browser using JavaScript. The generated passwords are not sent | ||
| over the internet or stored on a server. The passwords are | ||
| generated locally on your device and are not shared with anyone. | ||
