Setup SSH access with SSH keys -- No passwords for login
So, you're tired of putting your password in to SSH to gain access? You ask, "Isn't there a way so that this can be secure but still not require me to input a password?" Indeed, there is a way. That way is using SSH keys and the following will detail how to setup it up.
PuTTY
Setting it up with PuTTY is easy as a few clicks.
- Make sure you have all of PuTTY's applications -- you'll specifically need PuTTY, Pageant, PuTTYgen.
- Launch "PuTTYgen"
- Click "Generate" button to start the key generation process
- Input a comment -- something useful but short
- Input a passphrase -- the private key will encrypted and it's important to have a passphrase
- If you're sure no will ever get access to your private key, then you can leave the passphrase out. If you do this, however, you may want to put the private key file on a USB flash drive or something external from your computer and in a safe place.
- Click the "Save public key" button and save the public key to the desktop -- for easy access
- Click the "Save private key" button and save in a safe and secure place -- it's important never to give this key to anyone and do NOT store it on the server.
- Login to SSH using your password
- Type the following command:
- nano ~/.ssh/authorized_keys
- Open the public key file and copy ALL the contents (Control C)
- Go back to PuTTY and right click the mouse -- this will paste the public key in.
- Save the file by doing "Control O" and exit nano by doing "Control X"
- Logout of SSH
- Launch "Pageant"
- Click "Add key" button and navigate to the private key file.
- If you inputted a passphrase, it will ask for it at this point.
- Open PuTTY and login to SSH -- It should ask for the user but then it should login using the SSH key.
- You're done, congrats! Now if you want to login to multiple accounts using the SSH key, just copy the public key file to the other accounts and login as usual.
