Adding a Second SSH Key to a Remote Host

Korey Hinton –> My Blog –> Server –> Adding a Second SSH Key to a Remote Host

March 5, 2014

I always find that I run into some kind of problem whenever I try to add a new client computer to have automatic passwordless key access. So I decided to clearly document each step to adding a new client computer.

1. New Local Client



Copy the .pub file it saved on the new client over to the old local client.

2. Old Local Client (that has ssh access already)

scp ~/.ssh/


3. Remote Server

# create a backup
cp ~/.ssh/authorized_keys ~/.ssh/backup

# append key
cat ~/.ssh/ >> ~/.ssh/authorized_keys

Now you should be able to ssh from the new local client to the remote server.
