+### SSH Repositories
+
+For SSH-based git repositories, you can use SSH keys for authentication.
+
+## SSH Authentication
+
+Authenticate with SSH-based git repositories using encrypted SSH keys.
+
+### Adding SSH Keys
+
+1. Go to **Settings > Credentials**
+2. Click **Add SSHKey**
+3. Enter key name and paste your private key
+4. Optionally add a passphrase for encrypted keys
+
+### Host Key Verification
+
+When connecting to an SSH server for the first time, you'll be prompted to verify the server's host key fingerprint. This prevents man-in-the-middle attacks.
+
+The verification dialog shows:
+- Server hostname and IP address
+- SSH key type and fingerprint
+- Warning if the key has changed
+
+### Passphrase-Protected Keys
+
+If your SSH key is passphrase-protected, you'll be prompted to enter the passphrase when needed. Passphrases are not stored and must be entered each time the key is used.
+
+### Custom SSH Ports
+
+SSH repositories using non-standard ports are automatically detected. The port is extracted from the URL (e.g., `ssh://user@host:2222/repo.git`) and used for authentication.
+
+### Known Hosts Management
+
+Accepted host keys are stored securely in the database. If a server's key changes, you'll receive a security warning before proceeding.
