PassGen is a password generator application that helps generate encrypted passwords with combinations of letters, numbers and symbols instantly. The IT Engineers have an option to include the type of parameters that are present in the password.

---

Steps to generate a password

1. Select the required parameters for the generation of the password.

• Length - Choose the number of characters of a password. The IT Engineers can specify any value for the length field.

  1. Count - Multiple passwords can be generated at the same time which helps in saving time.

  2. Different types/combinations of characters can also be chosen as an option.

1. Once the parameters are set, click on the Generate button. A password will be generated which can be utilized by the user for the required purpose.

Advantages

• The application has a user-friendly interface and is easy to use.

• This particular generator does not store the passwords as a log in the backend hence providing stronger security for the users.

• A lot of time is saved with this instant password generator.
