Obtain username for shinyapps.io

[Robin Davies]

Hi, I have seen this question a couple of times but I am still a bit unclear.  I would like to obtain the username and then take actions on this. For example, the user currently on the app is joebloggs so only show data that joebloggs is permitted to see.  Can one only get a username through Shiny Server Pro? I don't use Linux or Redhat so I am a bit stuck...

I would start with the shinyapps.io documentation first, and then follow it to the article on Shiny permissions.

If you have further questions about hosting your application on shinyapps.io, this would be the appropriate list.

If you have questions about Shiny itself, I would suggest following up on the shiny-discuss group.

Thanks Joshua

That's the route I followed but I am still struggling.  The Shiny permissions documentation and other web searches only talks about extracting the session$user from a Linux/Redhat server.  I am wanting to extract the username from the person logged into www.shinyapps.io (or return a NULL if they are viewing my app as a guest).  I'm really hoping this feature is possible, otherwise my app is at a dead end.  Perhaps shinyapps have done this to protect the user's identity (security).  Alternatively, is it possible to determine if the user has logged in on shinyapps.io, I might be able to use this as a workaround?  If you have any other ideas on solving this, it would be greatly appreciated.

Robin,

If you're running on shinyapps.io, and your application is set to private, when a person logs into your application the email address of the person who is logged in will be in session$user. We don't expose anything other then the email address. Again this is for private applications only.

Hope that helps,

-Andy

Gosh that looks promising.  I am currently tinkering with the free version.  I am assuming this feature is only available from the basic version up and not the starter version?

Robin,

Private applications are available in the Standard plan and higher.

You can check out the different options on our website: http://www.shinyapps.io/#pricing

Best,

Hi, 

I was looking for an answer to this questions for quite some time now, but I gave up and built a simple login screen for non-pro shiny apps (free version of shinyapps.io). I created a list of users (username, passwords, email address, and set the authorization level - user vs admin) in google sheets. Using the googlesheets package (auth, tokens, etc.), the list of users are fetched on app load and the app can load from there.

I'd be happy to post an example, but wanted to make sure I understood your question correctly.

Is this what you're looking for?

Best,

David
