For anyone wondering - why would I need it? I'm already signed in to github, the commit is commited using my ssh-key, Github knows it's me. Why would I need another verification?
Here's why. https://dev.to/martiliones/how-i-got-linus-torvalds-in-my-contributors-on-github-3k4g . If someone commits with your email (or github noreply email, which is public), it will get attributed to you. I was just trying it with colleauges account, and so far I haven't found any way how to tell that it really wasn't him.
This made me wonder - is there any active Best Of community on any instance? This would be a perfect candidate.
