It might be a common case that you have multiple github.com accounts (personal and professional), and you want to use different ssh keys for different github accounts, as github.com does not allow same ssh key for different accounts with “Key is already in use” error.
To achieve this, you could follow this tutorial:
- Generate ssh keys for each github.com account. For e.g.
~/.ssh/configfile to specify which ssh key to use for which github account.
Host github.com HostName github.com IdentityFile ~/.ssh/id_rsa User copdips # The HostName is still github.com, but the host here is github.com-pro, this is the key point. # You can change it to whatever you want Host github.com-pro HostName github.com IdentityFile ~/.ssh/id_rsa_pro User copdips-pro
- Git clone the repositories by replacing
github.comin the git clone ssh url with the ssh alias defined in
~/.ssh/config. Say the pro ssh clone url is: git@
github.com:my-company/repo.git, than you need to rewrite it to git@
github.com-pro:my-company/repo.git to be able to use the ssh key
In Chrome (so as to Edge), there’s an extension called MultiLogin that allows you to use multiple accounts (for e.g. personal and professional github.com accounts) across different tabs in the same browser instance. So you do not need to keep two browser instances opened at the same time. In Firefox, you even have a better extension called Firefox Multi-Account Containers.
