How to have Email Authenticated Field in an existing Database of Email addresses

    Hello, we're attempting to create a form that essentially requires a user to authenticate their email against an existing list or database of email addresses.  Is it possible to create a field that references an outside database?  Is SSO an option?

    Hi Alex,

    Thank you for contacting us.

    First, I also recommend signing up for a JotForm account(for FREE) if you haven't done so yet. You can use this link to signup using your email account.


    As to your current inquiry, you may want to check these 2 widgets that have email authentication/verification function

    #1. XVerify Email


    #2. E-mail Validator


    Hope this help. Let us know if you need further assistance.

    Hi Jonathan. 

    I think what Alex meant to ask is if the email addresses that their users enter on the form can be authenticated / checked (if it exists or is valid) from an external list or database.

    He also wanted to know if single sign on (SSO) is supported by JotForm forms.

    At the moment there is no provision to verify an email against database records, you can however achieve this by downloading the form's full source code then writing Ajax calls between the field and your custom database.

    At the present jotform does not have SSO option available
