Even better, most implementations of the technology don't require an account of any kind. Chats take place on a web page that you set up on a site that supports webRTC. To get chatting all you have to do is share a link to the web page and you'll be up and running in no time. Talk about hassle free!
If you'd like to give webRTC a try, here's how to get started.
Your browser
Many current browsers for the PC support webRTC, including Chrome, Firefox, and Opera. Apple's Safari doesn't and neither does Microsoft's Internet Explorer; however, Microsoft-owned Skype plans on supporting webRTC in the future with its newly announced Skype for Web project.If you want to go mobile Chrome, Firefox, and Opera support webRTC on Android. On iOS you can try Bowser.
Get chatting
Once you've got your browser picked out it's time to start using webRTC. Sites that support webRTC include appear.in, talky.io, and apprtc from webRTC.org.Most of the sites that support webRTC are incredibly easy to use and don't require a lot of technical prowess. For our purposes I'll just show you one example and leave it to you to apply that knowledge to another service.

Now all you have to do is share the link to the web page you're on, wait for others to join, and you're ready to go.

In the case of Firefox, after you click the chat button, click the Start a conversation link. A pop-up window will appear in the bottom of Firefox asking you to name the conversation and then giving you the opportunity to email or copy the link to the chat's web page.
Just to be clear, it doesn't matter if you use Firefox and your chat buddies use Chrome or Opera. As long as everyone is using a browser that supports webRTC there shouldn't be any compatibility problems.
That's about all there is to webRTC. In my experience, the call quality isn't quite as good as you'll experience on Hangouts or Skype, but it'll get there eventually. In the meantime, happy chatting.
