Generate SSH key

Github

Full instruction is here.

1. Run command.

ssh-keygen -t ed25519 -C "your_email@organization_domain"

2. Specify filename in %USERPROFILE%/.ssh/github.
3. Add generated public SSH key into Github account. Instruction.

Bitbucket

Full instruction is here

1. Run command

ssh-keygen -t ed25519 -C "your_email@organization_domain"

2. Specify filename %USERPROFILE%/.ssh/bitbucket
3. Add generated public SSH key into Bitbucket account. Instruction

Gitlab

Full instruction is here

1. Run command

ssh-keygen -t ed25519 -C "your_email@organization_domain"

2. Specify filename %USERPROFILE%/.ssh/gitlab
3. Add generated public SSH key into Gitlab account. Instruction

SSH-agent

1. Kill SSH-agent if exists and run in the background

killall ssh-agent; eval "$(ssh-agent)"

2. Add private SSH keys to the ssh-agent

ssh-add ~/.ssh/github
ssh-add ~/.ssh/bitbucket
ssh-add ~/.ssh/gitlab

3. Optional. Copy SSH keys into the Windows directory or any other WSL

cp -b ~/.ssh/github /mnt/c/Users/%USERPROFILE%/.ssh/
cp -b ~/.ssh/bitbucket /mnt/c/Users/%USERPROFILE%/.ssh/

4. Test your connection

ssh -T git@github.com
ssh -T git@bitbucket.org
ssh -T git@gitlab.com

Configurate ssh-agent for multiple SSH keys

The next steps should be done in each environment where you need access to Git (Windows, WSLs, etc.)

1. Create config using nano

nano ~/.ssh/config

2. Put the next config into %USERPROFILE%/.ssh/config

Host github.com
        HostName github.com
        User git
        IdentityFile ~/.ssh/github

Host github.com-username
        HostName github.com
        User git
        IdentityFile ~/.ssh/username

Host bitbucket.org
        HostName bitbucket.org
        User git
        IdentityFile ~/.ssh/bitbucket

Host gitlab.com
        HostName gitlab.com
        User git
        PreferredAuthentications publickey
        IdentityFile ~/.ssh/gitlab

3. Optional. Copy SSH config into each environment

cp -b ~/.ssh/config /mnt/c/Users/%USERPROFILE%/.ssh/

4. Set up autostarting ssh-agent
   1. Update %USERPROFILE%/.profile on the next way using:

      nano .profile

   2. In the end of the file, put the next

   if [ "$BASH" ]; then
   if [ -f ~/.bashrc ]; then
   . ~/.bashrc
   eval "$(ssh-agent -s)"
   fi
   fi
   
   mesg n 2> /dev/null || true

Cloning repositories using different accounts

By default,

git clone git@github.com:organization/remote-repository.git
git clone git@bitbucket.org:organization/remote-repository.git
git clone git@gitlab.com:organization/remote-repository.git

For specific account,

git clone git@github.com-username:organization/remote-repository.git
