The Anon User URL is IP driven therefore if you are working offsite, the anon user will need to be logged in remotely to your organisation, OR another option is they can use a mobile device to access a 'one time access token'. See attached for instructions.
Users with log-in credentials for Prompt will be able to easily access Prompt anywhere by searching https://app.prompt.org.au and inputting their username and password in the log-in page.
If you would like to enable easier off-site access for your anon user, we could disable the IP and change the URL to an 'access token'. Some organisations have chosen this option. The drawback is that anyone who has access to the token will be able to access your anon user search page.
