Tick this option to make your form accessible to the public without them being required to login.
Tick this option to allow form submissions only from people who have logged in. This is useful when you want to verify the identity of those who are submitting your form, but don't want to restrict who specifically can submit the form.
Tick this option to allow form submissions only from specific people who have logged in. This is useful when you want only specific people to have view/submit access to your form. After ticking this option and saving your changes, to specify who those specific people are with view/submit access to your form please go to the "Users" tab and grant your specific users "Submit Form When Login Protected" access rights.
Tick this option to allow form submissions only from people who have a password which you have supplied them with. If you wish to require a password field and also require people to be logged in, that is also allowable.
Note: Your password can contain any combination of numbers, and uppercase or lowercase letters
This option enables Google Invisible Captcha protection on your form to block automated spam submissions. In most cases your form users will not need to click on anything, but if a users behaviour seems suspiciously similar to a SPAM BOT, then an additional question is automatically included at the end of your form which only a human can reliably answer, and makes it extremely difficult for automated spam bots to submit your form with automated junk submissions.
