Using the slider you can create a strong random password of up to 64 characters, 4 being the smallest. I would recommend a password of up to 15 characters as strong.
You can select letters, mixed case, punctuation, numbers in your password.
You can try a strong random password generator tools here. There are over 14 different websites for you to choose from like Norton.
You can copy your password directly on the website. The default length on the site is 20 characters which is good.
