you can delete all cached keys before

$ ssh-add -D

finally, you can check your saved keys

$ ssh-add -l

	User rajendar@company1.com
	IdentityFile ~/.ssh/id_rsa_company1

#company2 account
Host company2
	HostName company2.com
	User rajendar@company2.com
	IdentityFile ~/.ssh/id_rsa_company2

$ git config user.name "rajendar"
$ git config user.email "rajendar@company1.com"
