Adding 50 - 100 new users for read only - Best practices for adding outside company members

Do you know the benefits or drawbacks of adding 50-100 users to read only some reports I am creating for people outside our company?

Here are the two scenarios and would like to know what the best way to approach this with the cons and pros to it.

1. Setting up 50 – 100 users under the @companyname.com portal/name with read only ability and only access to certain reports we want them to read.

• Pro – The benefit will be we can see their usage numbers of the certain reports.
• Pro – Also more security and control under if they can see the reports.
• Con – Having to manage 50-100 new users names & passwords.

Are there any other Pro or Cons for setting this up this way? Is there a best way to manage all these users and passwords you would suggest as we are a small company?

1. Have the 50 – 100 users setup Power Bi Pro licenses on their own. How do we give them access to these reports when their domain is outside our company?
• Pro – Don’t have to manage the passwords or User name and security levels for these new users?
• Less control

Is this even a strategy you would suggest? And if we were to give them access to the reports how do I set that up?

Thanks for any advice and help!
