There are different ways to let your users create a new account:
1. Login page auto-checking (recommended)
Both the form and portal allow you to have a login page. Which could also enable new signups. Go to:
Table settings
Add a login screen to your form or Require users to log in to use portal
If record does not exist
Create a new record for the user
This option allows users to create new profiles to sign up if they don't exist already.
2. Link on the login page
You can add a link for the user registration form to the portal's login page. You can set this up in Login Page Subtitle. Here's an example:
3. Link in an email
You can also email users a link that takes them directly to the registration form. You would need to set up one first.
💡Note
The login info is not stored in the extension itself. They are records in Airtable. The login fields would be columns in your users' table.
