How to reset the SSH of RSA key on MAC


1. Clear the contents of your ~/.ssh directory and set the directory permissions to 600
$ rm ~/.ssh/*
$ chmod 600 ~/.ssh
2. Generate your rsa key pair (there are variations for this, but this is the version I used):
$ ssh-keygen -t rsa
3. Set the permissions for all files in ~/.ssh to 600
$ chmod 600 ~/.ssh
4. Copy your id_rsa.pub key to your server’s .ssh/authorized_keys file
5. Add your passphrase to your keychain using this command:
$ ssh-add -K
(you will see Enter passphrase for [your system]/.ssh/id_rsa: )
6. You are all set to login using ssh without a password
