You can select password characters and also has the option to select or deselect uppercase test, lowercase text, numbers and symbols. It can be used to generate passwords like this: bx8hnv7ueuwugbqg7pz8f8n12c7g9qfbn9q12, which is more secure and unhackable. You need to save it in a safe place. I recommend you to use 12 characters long password because it's more secure than smaller passwords.
