Password Generator

To use the password generator, click on the "Generate" button.

The checked character sets will be used to compose the password.

Click the button until a satisfactory password is generated.

Using Custom Characters

The characters from which the password is composed are any checked character sets plus what is typed into the "Custom characters" field.

If all checkboxes are unchecked, only the characters in the "Custom characters" field are used to compose the password.

If any characters in the "Custom characters" field are repeated, they are more likely to be used in the password composition.
