Online hacking is becoming increasingly sophisticated, leading to frequent password and login information theft. This can become extremely inconvenient, and it can even lead to the loss of money or sensitive personal information if your passwords fall into the wrong hands.

Unfortunately, most stolen passwords are relatively simple and easy to crack. Things like names, birthdays, hobbies, and favorite pets aren’t good password material, and using them is just asking for trouble.

That’s where password generators become useful. In this guide, we’ve analyzed five of the best password generators available today. Among other things, we’ve looked at the pros and cons, ease of use, and security features of numerous programs to bring you this list, so you can rest assured that it’s comprehensive and accurate.

Note that many of the programs listed below offer some sort of password manager alongside their password generators. There is also a mixed selection of free and paid options.

Here, then, are the best password generators currently available.

LastPass offers a powerful, secure password generator that’s 100% free and backed by a range of additional features. It’s available both online through the LastPass website and within the LastPass app. With it, you can specify exactly what sort of password you want to create.

For starters, you will be asked to specify the length of your password, which can be anything from one to 50 characters long. You can choose from passwords that are easy to say (without numbers or special characters), easy to read (without confusable characters like 1 & l), and standard (all characters). You can also specify which combination of uppercase and lowercase letters, numbers, and/or symbols you want to use. Once a password has been generated, a neat color-coded bar indicates its strength.

Alongside its password generator, LastPass also offers one of the best password managers on the market. New passwords can be imported directly to the manager, which comes with a range of advanced features.

Simple online password generator

+Secure random password generation+Export passwords to different devices
Reasons to avoid
-No integrated password manager

With the Strong Password Generator, the name says it all. This simple yet secure online program is designed to create unbreakable passwords at the click of a button. All new passwords are created locally on your computer, which means they aren’t ever stored online or on the program’s servers.

On top of this, the Strong Password Generator allows you to specify the length and composition of your new login. In theory, you can create passwords that are as long as you want. During our testing, we were able to easily generate a random string up to a million characters long in a matter of seconds—not that you would ever need one of this length.

In addition, you can specify what type of characters you want your password to include. Choices include alpha upper (A–Z), alpha lower (a–z), numbers (0-9), and symbols. Each new password comes with a unique QR code so you can transfer it to a phone or tablet as required.
