&lt;p&gt;The explorer will use the default store to persist the credentials to access the UI and the API. If no values are set, the first invocation will set a randomly generated pair of username and password under the kv-credentials key, with the value following the user:password format. On the first run, the values will be printed in the logs, and they can be used to log in and change them (creating a new credentials value will override the existing value).&lt;/p&gt;
&lt;p&gt;&lt;em&gt;Known limitations&lt;/em&gt; 
the explorer can only be used with Spin’s default key/value store. When this will be configurable, this component will support working with custom stores as well.&lt;/p&gt;
