Get Your Username and Password for Your Trailhead Playground

In the previous step, you uploaded an audio file. Now you install a Lightning Web Component that makes the sound play. To complete the installation, you need the username and password for your Trailhead Playground. 

If this is your first time installing a package, you might want to check out the Trailhead Playground Management module first.

  1. From Setup, enter users in the Quick Find box, then select Users.
  2. Locate your name on the list of users. Check the box next to your name. Make note of the username. This is the username for your Trailhead Playground.
  3. Click Reset Password(s) and OK. This will send a password reset email to the email address associated with your username. Be sure to check your spam folder if you don't see the email.
  4. Click the link in the email.
  5. Set your password.

Now you have your username and password for your Trailhead Playground.
