+# Default Username And Password For New Instance
+
+Let's say you've set up a fresh new instance of MySQL. Perhaps in a docker
+container with a MySQL image. When you first connect to the instance, you'll be
+prompted for a username and password.
+
+What is the username and password for a MySQL instance you've just created?
+
+There are defaults. The default username is `root` and the default password is
+left blank.
+
+So, your connection URL will look something like this:
+
+```
+mysql://root@localhost:3306
+```
+
+You can use that on the CLI or plug it in to the connection details panel of
+your favorite SQL client.
