ElMO

Multiple git account in the same computer (Windows)

Set gitconfig

Global config: default path C:\Users\Elmo\.gitconfig

[User]
    name = elmo_aaa
    email = elmo@aaa.com

[includeIf "gitdir/i:D:/Note/"]
    path = D:/Note/.git/config

Specific project config: D:/Note/.git/config

[User]
    name = elmo_bbb
    email = elmo@bbb.com

Generate SSH Key for specific account

ssh-keygen -t rsa -C "elmo@bbb.com"

the default path is C:\Users\Elmo\.ssh

it can't use the default name in the default path because it will replace the original account SSH key

finally, copy the content of public key and paste in GitLab SSH keys
