How do I create a password?

Do you mean you want to create a password field on your forms or a password to let users access your form(s)?

It's not possible to create any sort of password field for your forms because that would violate our terms of usage and result in suspension of your account due to phishing for sensitive information such as with or for password and username account creation as an example of that.

Aside from that though so long as it is not intended to be used in any situation similar to the above you could allow code creation or something of the sort which is allowed so long as it is not collected or used for any similar instances as mentioned above.

You could also even use a special code or link to give to users to access your form.
