Preparation - SSH Keys

An SSH key lets your computer sign in securely to your GPU instance without a server password. Before creating an instance, add your public key to Geodd. Your private key stays on your computer.

Before you start

If you already have an SSH key, you can reuse its public key instead of generating another. The public key file ends in .pub; the similarly named file without .pub is private. Never paste your private key or passphrase into Geodd.

The commands below use the default Ed25519 key location. If your existing key has another name or location, use its .pub path when copying. If ssh-keygen says a key already exists, answer n to avoid overwriting it, then copy the existing public key.

Windows PC

1. Open PowerShell from the Start menu.

2. If you do not already have a key, run:

   powershell1 line

   Copy

   ssh-keygen -t ed25519

   Press Enter to accept the default file location. Choose a passphrase to protect the private key, then enter it again to confirm.

   If ssh-keygen is not recognized, install OpenSSH Client through Optional features in Windows Settings, then reopen PowerShell. You do not need OpenSSH Server.

3. Copy your public key to the clipboard:

   powershell1 line

   Copy

   Get-Content "$env:USERPROFILE\.ssh\id_ed25519.pub" | Set-Clipboard

4. Return to Add SSH Key in Geodd and paste it into Public Key Content.

Mac

1. Open Terminal from Applications > Utilities, or search for Terminal using Spotlight.

2. If you do not already have a key, run:

   Shell1 line

   Copy

   ssh-keygen -t ed25519

   Press Enter to accept the default file location. Choose a passphrase to protect the private key, then enter it again to confirm.

3. Copy your public key to the clipboard:

   Shell1 line

   Copy

   pbcopy < ~/.ssh/id_ed25519.pub

4. Return to Add SSH Key in Geodd and paste it into Public Key Content.

Add the key to Geodd

If you opened this guide from the creation dialog, return to that tab. Otherwise, open SSH Keys and choose Add SSH Key.

Enter an identifier name, such as work-laptop, and paste the complete public key. It normally starts with ssh-ed25519 or ssh-rsa. Select Save Key. Adding a key does not deploy or charge for an instance.
