## Q: How to use an ssh-agent?
Using an SSH-Agent will make your connection even safer, as your private key is encrypted with a passphrase. To create a ssh-key goto [How to use ssh-key authentication?](#How-to-use-ssh-key-authentication?).
Continue with how to use the ssh-agent:
```bash
# Launch the SSH Agent
eval`ssh-agent`
# this will add your ssh-keys from ~/.ssh/
# You will be asked a passphrase if you have one
# this will add .ssh/id_rsa as default
ssh-add
# or any keyfile you created:
ssh-add .ssh/secret_key
# Copy the ssh-key (pub) to the server
ssh-copy-id [user]@[server]
# and connect
ssh [user]@[server]
# Kill the agent and all store secure information
ssh-agent -k
```
**Tip: configure your `.ssh/config` file to use the correct key a server. Goto [SSH](SSH.md)**
