SSH keys

ssh

Connecting to GitHub with SSH - User Documentation
Generating SSH keys - User Documentation
Error: Permission denied (publickey) - User Documentation

You can get your keys via https://github.com/username.keys.

Multiple accounts

If you have multiple account on GitHub, you can use HTTPS to specify the user (but you have to enter credentials every-time):

git remote set-url origin https://USERNAME@github.com/USERNAME/PROJECTNAME.git

You must use git user (not USERNAME) for git protocol; you can then use multiple SSH keys with SSH host alias to distinguish between different accounts.

see git-notes.md#specify-ssh-key-to-use

~/.git/config:

# Personal GitHub
Host github.com
  HostName github.com
  User git
  IdentityFile ~/.ssh/id_rsa
  IdentitiesOnly yes

# company GitHub
Host github-COMPANY
  HostName github.com
  User git
  IdentityFile ~/.ssh/id_rsa_COMPANY
  IdentitiesOnly yes

> ssh -T git@github.com
Hi <personal username>! You've successfully authenticated...
> ssh -T git@github-COMPANY
Hi <company username>! You've successfully authenticated...

# replace @github.com with host alias (@github-COMPANY)
> git remote set-url origin git@github-COMPANY:Company/testing.git
# or manually edit `.git/config`
