I created a collector app and shared all of the content (Feature, service definition, Web Map, Dashboard) with a group in ArcGIS Online. Then I sent out invitation to the group. My question is rather than sending out 20 different invitation to the group and having to manage all of those accounts. Can I create a single account (Username and password) and have multiple people out in the field use that account to collect data using the collector app. Would having multiple people collecting data simultaneously using the same account-affect the data quality and integrity. What is the best solution to this problem?
