→Option 1 (Amahi 7/8 ONLY)
Using ''putty'' logon to our Amahi HDA using the profile you created earlier.
=== Option 1 (Amahi 7 or greater '''ONLY''') ===
We can add the key file to the HDA using the HDA dashboard.
Navigate to the '''Users''' tab
[[File:User-SS0.png|700px]]
Select your user and you should see ''Authentication''.

Click the key and paste your key information. Choose ''Update Key'' when finished.

Proceed to [[Key-Based_SSH_Logins#Configure_PuTTY_to_use_the_private_key|Configure PuTTY to use the private key]]
=== Option 2 (All Amahi versions) ===
We must now create a directory and file in which to store our public key
<div style="border: 1px solid #A3B1BF; padding: .5em 1em; color: #000; background-color: #E6F2FF; margin: 3px 3px 1em 3px;">chmod 600 ~/.ssh/authorized_keys2</div>
==Configure PuTTY to use the private key==
To generate a new SSH key in a client computer used to login to Amahi, do this:
<div style="border: 1px solid #A3B1BF; padding: .5em 1em; color: #000; background-color: #E6F2FF; margin: 3px 3px 1em 3px;">
</div>
It should say something like this (on Mac OS X). Press enter to choose the default:
<div style="border: 1px solid #A3B1BF; padding: .5em 1em; color: #000; background-color: #E6F2FF; margin: 3px 3px 1em 3px;">
</div>
Enter a passphrase. It's not secure to leave it empty. To avoid having to enter the passphrase every time you can use the [https://en.wikipedia.org/wiki/Apple_Keychain Mac OS Keychain] in Mac OS or an ssh-agent on Linux:
<div style="border: 1px solid #A3B1BF; padding: .5em 1em; color: #000; background-color: #E6F2FF; margin: 3px 3px 1em 3px;">
</div>
Then enter it again
<div style="border: 1px solid #A3B1BF; padding: .5em 1em; color: #000; background-color: #E6F2FF; margin: 3px 3px 1em 3px;">
</div>
This will give you something like this:
<div style="border: 1px solid #A3B1BF; padding: .5em 1em; color: #000; background-color: #E6F2FF; margin: 3px 3px 1em 3px;">
</div>
service sshd restart</div>
= Tip Tips =Then * Recommend you check out [[Secure_SSH_against_brute_force_attacks|secure SSH against brute force attacked]] guidance to protect your HDA. * Monitor SSH access to your HDA by following the [[SSH_Email_Alerts|SSH email alerts]] tutorial. * In Amahi 7, you can put add the '''public''' (not the private key) in your Users area in your Amahi server to login securely with ssh and without a passwordof the HDA dashboard.
