Random Password Generator

This tool can generate secure, strong, random passwords. To ensure security, the password is generated completely on the webpage without being sent across the Internet.

A password is typically a string of characters that may include letters, numbers, and symbols that can be used to access something, typically an account, and prevent others from accessing it. In today's Internet age, it is likely that most people have experience with having a password for some kind of account. As such, it is important to understand how to construct a strong password (or use a password generator) as well as to understand how to take measures to safeguard the password.

Password strength

A password's strength indicates how well it can withstand guessing attempts or brute-force attacks. Password strength is typically an estimation of the average number of attempts needed to correctly guess the password, though it can vary. The password's length, complexity, and unpredictable nature all have an impact on this. For instance, a password would probably be weak if it contained a person's name, birthday, or other details about them that are normally not all that difficult to discover.

In addition to the password itself, effective security measures are crucial in lowering the chance of a security breach. Protections put in place to identify, thwart, or reduce security hazards are included in security controls. This includes safeguards like two-step authentication for your password or the ability to temporarily lock your account after a certain number of failed login attempts.

How to create a secure password

You can create a secure password by adhering to a few guidelines that are intended to improve password security. Security mostly entails creating a secure password, but it also includes steps like updating passwords on a regular basis, being aware of common passwords, and avoiding using them (password, 123456, qwert...). The following guidelines can be used to make 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 – 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
Also, many password policies typically include a minimum password length because generally, the longer a password, and the larger the variety of character types, the more secure the password.

The user of this website has the option to eliminate confusing characters from the random password generator. This includes symbols like the letters "L" and "I," which might be challenging for computers to differentiate. In the case of utilising a random password generator, this is very important. In some circumstances, it might be challenging to distinguish an upper-case I from a lower-case "L" or the number 1. Ambiguous characters may cause confusion, which could result in the user being locked out of their own account. But keep in mind that character exclusion typically reduces a password's potential strength.



Password entropy


The password generator also determines the password entropy, measured in bits. The higher the entropy, the more difficult it will be for the password to be guessed. In the context of a brute force search (where every possibility is tested), a password entropy of 100 bits would require 2100 attempts for all possibilities to be exhausted. On average however, about half of these possibilities would need to be exhausted before the correct one is found in a brute force search.


How to protect your password

Creating a strong password is vital, but so is protecting it. The steps you can take to help protect your password are outlined below. There may be other steps one can take, however the following are just a few tips that could be useful:

. Don't tell anyone else your password. The user should ideally be the only one who knows their password. For instance, even if you have complete faith in the person to whom you divulge your password and even if they have no other motivations, they might not be as vigilant in keeping it safe as you would be. The more people who know your password, the more likely it is that someone else will steal your information.


  • 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 frequently - Although this is another inconvenience-filled step you may take to keep your accounts secure, it should potentially assist. This is useful in situations where someone might get your password and access them, but not necessarily try to do something bad right away. If you change your password under these circumstances, it would prevent them from accessing your account for as long as possible, presuming they are unable to figure out the new password. Changing your password would prevent someone from utilising a remembered password if you had saved it on an old device that you may have sold or thrown away.
  • 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.
