Issues With Trying To Use Magit Mode For GitHub Repos Via SSH Key

[Samuel Banya]

Hey there,

I'm trying to move all my personal Git repos back to GitHub.

I am having a difficult time doing so since I'm getting some weird side effects 
of either Git or Magit Mode acting weird.

Here's what I did:
- I made a single repo on my GitHub that's blank
- I then cloned the repo locally on my machine
- I then added the contents of the older repo (minus the '.git' directory) to 
the the cloned directory
- I then added all of the new folders and files to that particular repo via 
'Magit' mode in Emacs
- I then attempted to push a commit to that new GitHub repo
- I was then prompted for a 'Username' and 'Password', which kept defaulting to 
using '@github.com' --> example: I would put 'Tom' --> it would change to 
'tom@github.com' for the username. This even occurred even if I used the email 
I have for my GitHub account, 'tom@mail.com' --> 'tom@mail.com@github.com'
- I did some research and apparently GitHub changed their authentication 
methods to force either a Personal Access Token or through an SSH key
- So, I simply added my SSH key to my GitHub account, specifically the 'public' 
key (id_rsa.pub)
- However I'm getting the same weird results as above

I believe I have to modify the .git/config'* *file so that the 'url' is changed 
accordingly.

However, I'm a bit confused on actually WHAT to put in there.

Here's an example (not the actual line I used):
url = ssh://git@github.com:Tom/example.git

Also, I have this present in my ~/.ssh/config file as well:
Host github.com
  IdentitiesOnly yes
  IdentityFile ~/.ssh/id_rsa.pub

Any ideas on what I did wrong? 

The only thing I can think of is that I made a blank GitHub repo to begin with, 
so my workflow is probably messed up as a result.

Any reference links would be cool too since I haven't used GitHub in ages in 
comparison so I have no idea how to approach this.

Just wanted to push my git repos to GitHub quickly.

Thanks,

Sam
