Set up Discord
Discord needs a verified email or phone number before you can use the MLB server. It takes about 2 minutes:
Step 1
Install the Discord app
Get it free from your phone’s app store.
Step 2
Verify your email or phone
Open Discord and sign in. At the top you’ll see a yellow “Verify Email” banner — tap it, then open the email from Discord and click the link. (Or add a phone number under Settings → My Account.)
Step 3
Come back and connect
Once your Discord shows as verified, come back here and tap “Sign in with Discord” again.
