Signals Notebook: Access Expired/Authentication Error on password reset

One of the errors above is presented to the user after clicking on the “To Set Your Password” link provided in the "Welcome to Signals" email.

The two errors above are shown to the end user from a few different scenarios as follows:

1. The user took too long from receiving the reset password link to clicking on the “To Set Your Password” link. The resolution here is for the user to follow the Reset Password workflow again and click on the “To Set Your Password” link in the new email more promptly.
2. The user followed the Reset Password workflow multiple times, and clicked on the “To Set Your Password” in other than the most recent email. The resolution here is for the user to click on the link in the most recent email else follow the Reset Password workflow again and click on the “To Set Your Password” link in the new email.
3. If they click on the link provided but are not a user on that tenant. System Administrator should check if user exists on that tenant under Users > Current.
4. They may also get this screen if they ARE a user on this tenant, but are not set up on Auth0. In this case, if they follow the Reset Password workflow, they will repeatedly experience this error. A remedy here is to set them up on any other tenant and domain using Auth0 which will create them as a user in Auth0. Once that is done they ought to be able to complete the password reset process.
