I am logged into production. Trying to install (Box) from AppExchange into a sandbox. I can't get logged into the sandbox, though. It prepopulated Username, but my password isn't working.

I've tried a dozen different permutations of credentials following the advice of several threads here (notably, How to login into a sandbox from Sandboxes page in Production org?).

I've been trying to log in for a full hour and I'm no closer...

  • Has the sandbox been completed already? It's not still pending creation? Oct 3, 2016 at 19:10

Okay, this problem was that the sandboxes had been completed, but were not activated.

For future readers: You can check the 'auto activate' box when creating, else you'll get an email with a link to click to activate the sandbox.
