See the comment thread on this post. We require users to sign up for our platform, and they're confused by the "Sign in" option in our knowledge center. We can remove the Sign in option, but only at the cost of removing the ability to submit a ticket and disabling the web widget.
To quote another user: "There really should be a way to:
1. Allow anyone to email.
2. Remove the sign up button completely from Guide.
3. Allow all End Users access if part of an Org that has access OR Only allow verified users access.
Using this solution it would appear that anyone can still sign up and login to the Guide platform and relies on the content creators to ensure they select the correct visibility at all times."
