PasswordGenerator

As its name clearly states, PasswordGenerator is a useful Java-based utility that can help you instantly generate hard-to-crack passwords with just a simple click. As a bonus, the app also allows you to store multiple accounts alongside their credentials.

Apart from making sure that Java is present, getting started with the app is easy

Assuming that Java is already present on your computer's system, the application undergoes a streamlined and surprise-free installation process. Upon first launching the app, you are required to create an account by entering a name and a password of your choosing.
Only when this is dealt with, that you are greeted by the application's simplistic and intuitive, Java-specific user interface. Since there are no menus or hidden features and everything is right on display, you should be able to get comfortable using this app in the shortest time.

Store credentials and effortlessly generate passwords

This said, you can start adding accounts, alongside with the credentials like the account's name, username and password. Once you're done, you can either save the account or delete it thanks to a set of self-explanatory buttons.
The password generator is located on the right side of the main window and can help you to instantly create passkeys for all the accounts. Simply fill in the minimum and maximum character count numbers, as well as the number of digits you want for your password and hit the "Generate" button.
It is worth mentioning that you can also generate passwords using special characters by ticking the check-box or regenerate passwords until you find one that suits your tastes. Quite conveniently, you can easily transfer the generated password from the generator to your account with a simple click on the designated button.

Simplistic and non-impressive password generator

To conclude, PasswordGenerator is by no means the best tool of this sort out there, as most other apps of this sort have already evolved in multifunctional apps that have tons of other features besides their default one.
This said, if you are looking for a quick app for generating passwords that is both light on your computer resources and user-friendly then you might as well give this Java-based utility a quick spin.
The only thing to keep in mind is that since it is in a relatively young development stage, some bugs might be present, especially when generating passwords with extreme numbers of characters.
