Again, I'll mention briefly that if you're connecting to a public wifi network you might consider using a VPN just to be on the safe side. There's no major downside to doing this, and it may protect you from a 'sniffer' or 'hacker'. Now, I'm not paranoid about this -- just cautious. I use public wifi a lot in RV parks, for example.
One that I've downloaded and installed, and am using right now, is Windscribe VPN. Here is a review: https://securitygladiators.com/windscribe-vpn-review/ Now, I don't need a VPN on my home network, but am using Windscribe just to try it out. So far so good.
The free version gives one 10 GB of data/month, which is plenty for occasional use. Not only will it work on a PC or Mac, it will work on an iOS and Android device. And it is available as an extension for the Chrome Browser, which I installed as well. Installation of both the program and extension is dead simple.
And so far it is working great. Another aspect I like about Windscribe is it is based in Canada, and not another foreign country, many of which I don't trust. Here is their website: https://windscribe.com/
This morning, when I opened my computer, I noticed that it didn't connect to the internet right away, as it usually does. I looked at Windscribe, and it blocks access to the internet until I open the program. This is for my protection. It can be set to open every time I open my computer, which I haven't done yet.
To sweeten the pot even further, for a limited time one can buy the full, unlimited-data version, for only $50. See here. In theory, this is for 'lifetime' -- is that yours or theirs, one might ask? Of course there's a risk this VPN -- or any other, for that matter -- might close shop in the near future. But, all one is risking is fifty bucks, not the end of the world, if you purchase the full version.
If you have an interest, I'd suggest giving the free version a spin, then decide from there if you like it or not.
As with using any VPN it will slow your download connection some, but I haven't found it onerous.
