In order to facilitate the signup of your users, you might want to set up single sign on for your users.
You can also set up SSO via the SAML protocol using the following instructions: SAML 2.0 SSO
This process is really simple and straightforward. You need to be signed into the application as an admin user and go to
https://ACME.intuo.io/settings/integrations/intuo (where ACME is your intuo account name).
For Google apps users, you need to enable the integration labeled as google in the setting page. Since users are automatically created upon signup, you want to limit the domain that's allowed to sign in. Enter your email domain name (e.g. intuo.io) into the box and click the Save Changes button in the upper right corner.
Microsoft Azure/Office 365
In the settings page, scroll to the OpenID Connect section and enable the connection marked as azure. Enter the tenant (your Microsoft account identifier) in the text box and click the Save Changes button.
Hint: If you don't know where to find the Office365 tenant, follow these instructions: https://docs.microsoft.com/en-us/onedrive/find-your-office-365-tenant-id
Testing the connection
Sign out of the app by clicking on the button in the bottom left corner, and you should see a new button appear on your https://ACME.intuo.io/landing page. Depending on which connection you have set up, it will say Login/Register with Google or Login/Register with Azure.
After clicking on the button, you will go through a SSO process and be signed into intuo.
