I want my form security, email id authentication to access this form not other

UPDATE (August 20, 2019): Password protection feature is available now. 

Here is how it works:

1. Open the Form Builder and find the Enable Password Protection option under the Settings tab. 

2. If you select this option, you should set a password for the form. If you don't set any password, the Enable Password Protection option will be unselected.

3. When you set a password for the form, a person who wants to open the form will see this page:

4. If the person enters the incorrect password, s/he cannot open the form and will see this warning:

5. If the person enters the correct password, s/he can open the form and submit it. However, if you (form owner) change the password after s/he opened the form, s/he cannot submit the form and will see this warning:

6. You can reset the password by clicking on the RESET PASSWORD button or unchecking the Enable Password Protection option.

We do not have a password protection feature or access based on the email address. It is also not recommended to use a 'password' keyword on forms since we have a proactive anti-phishing filter. However, it might be possible to create something similar with a conditional logic on form. We can show the form fields when a code/email field is filled, see the next animation.

Result:

Note, this is not a real password protection. The access code can be found in a page source by advanced users.

Alternatively, you can add the password protection to your webpage where the form is embedded.

The form submission data is protected. You can only access it after the authentication to your JotForm account.
