How many users on pro plan

Hello, I have been trying to figure out which app plan would be right for my work team. Can someone tell me how many users you can have on the Pro plan? with a password protected app.

I believe you can only have one user at a time for a password protected app. I think what you want is a whitelist option where you can limit which emails can access the app.

With that in mind, Private Pro is the plan you need to choose.
