Access my dashboard from the Internet

Hi everybody.
Thanks for your attention.
I'm beginner in node red .I've made a project and I can monitor and control my system from a local dashboard.I want now to access to my dashboard over the internet (not only by using the same WiFi) with secure and for free.
Is there any one here can help me to solve this problem.

If you search the forum you should find numerous threads discussing the various options for doing this.

Including some over just the last few days. I've also recently added a flow to the flows site that shows you how to use NGROK reasonably securely to do this.
