How to tell Git which SSH Key to use - WPEngine Scenario with multiple accounts

config

#Examples of using WP Engine to setup repositories. If both sites are on the same account you can use the same private key.

#Windows user file c:\users\user\.ssh\config 

Host website1
   User git
   Hostname git.wpengine.com
   PreferredAuthentications publickey
   IdentityFile ~/.ssh/key_rsa
   IdentitiesOnly yes
   
Host website2
   User git
   Hostname git.wpengine.com
   PreferredAuthentications publickey
   IdentityFile ~/.ssh/key_rsa
   IdentitiesOnly yes
   
#Config file in GIT directory of local install website 1. We use "prod" as the alias for the remote
#Typical format for a WPEngine remote URL is [email protected]:production/websiteremote.git
#We can replace [email protected] with your host name setup.

#Here is an example of .git\config file for website1 project folder

[core]
	repositoryformatversion = 0
	filemode = false
	bare = false
	logallrefupdates = true
	symlinks = false
	ignorecase = true
[remote "prod"]
	url = website1:production/xxxprod.git
	fetch = +refs/heads/*:refs/remotes/prod/*
[remote "staging"]
	url = website1:production/xxxstaging.git
	fetch = +refs/heads/*:refs/remotes/staging/*

So we need to add .git/config in each project folder @eversionsystems?

[core]
	repositoryformatversion = 0
	filemode = false
	bare = false
	logallrefupdates = true
	symlinks = false
	ignorecase = true
[remote "prod"]
	url = website1:production/websiteremote.git
	fetch = +refs/heads/*:refs/remotes/prod/*

@khoipro Yes each project folder has it's own .git/config, that's the basis of how git works. The trick is setting up the SSH config to define multiple websites to use the same git user but assign different hostnames.
