SSH Without Passwords | Complete Guide for Linux, Windows, macOS | VS Code Remote for development

Stop typing your SSH password every single time! This is the ultimate 2025 guide to setting up passwordless SSH login using SSH keys on Windows, macOS, and Ubuntu. I'll walk you through the entire process step-by-step, from generating your SSH key pair to configuring your remote Ubuntu 24.04 server. The best part? We'll also configure the VS Code Remote - SSH extension to use these keys, unlocking a seamless, password-free remote development workflow directly from Visual Studio Code. This tutorial is perfect for developers, system administrators, and anyone looking to boost their productivity and security when working with remote servers. Learn how to set up SSH key authentication, use ssh-keygen, ssh-copy-id, and manually add keys to the authorized_keys file. By the end of this video, you will be able to SSH into your remote machines from your terminal and VS Code without ever being prompted for a password again! COMMANDS FOR COPY & PASTE: -- STEP 1: GENERATE YOUR SSH KEY PAIR -- (Run on your personal Windows, Mac, or Ubuntu machine) ssh-keygen -- STEP 2: COPY YOUR PUBLIC KEY TO THE SERVER -- METHOD A: FROM UBUNTU OR MAC (EASY METHOD) (Replace username and remote_host_ip with your details) ssh-copy-id username@remote_host_ip METHOD B: FROM WINDOWS (MANUAL METHOD) First, on your Windows PC, view and copy your public key. (Use the second command if your key file is named id_ed25519.pub) type $env:USERPROFILE\.ssh\id_rsa.pub type $env:USERPROFILE\.ssh\id_ed25519.pub Next, log into your remote Ubuntu server with your password and run these commands. mkdir -p ~/.ssh chmod 700 ~/.ssh touch ~/.ssh/authorized_keys chmod 600 ~/.ssh/authorized_keys echo "PASTE_YOUR_PUBLIC_KEY_STRING_HERE" ＞＞ ~/.ssh/authorized_keys (please type this command manually as the symbol ＞ is used because of youtube description restrictions) -- STEP 3: CONFIGURE VS CODE REMOTE - SSH -- (Open the SSH config file in VS Code and add this) Host your-server-nickname HostName your_server_ip_or_hostname User your_remote_username IdentityFile path/to/your/private/key Example IdentityFile path for Ubuntu/Mac: ~/.ssh/id_rsa Example IdentityFile path for Windows: C:\Users\YourUsername.ssh\id_rsa ============================================================ If this guide helped you speed up your remote workflow, please hit the LIKE button, SUBSCRIBE for more tech tutorials, and share this video! #PasswordlessSSH #VSCode #Ubuntu #SSH #Windows11 #macOS #Developer #RemoteDevelopment #linux tags(ignore): passwordless ssh, ssh without password, vscode remote ssh, vs code remote development, ssh key authentication, how to setup ssh keys, ssh-keygen tutorial, ssh-copy-id, authorized_keys, visual studio code remote ssh, ubuntu 24.04 ssh, ssh from windows to ubuntu, ssh from mac to ubuntu, remote development workflow, developer productivity, sysadmin, linux tutorial, ssh config file, windows 11 ssh, powershell ssh, terminal ssh, secure shell, public key authentication, devops, programming, coding setup, eliminate ssh password, ssh keys guide 2025, how to connect to server without password, remote coding, vscode tips, ssh tricks, linux server management, home lab, raspberry pi ssh, cloud server ssh, aws ec2 ssh, digitalocean ssh passwordless ssh, ssh passwordless, how to ssh without password, ssh keys, generate ssh key, ssh keygen, authorized_keys, ssh-copy-id, ssh config, vs code remote ssh, vscode remote, vs code passwordless ssh, ubuntu ssh, windows ssh, macos ssh, ssh tutorial, remote server, linux server, ubuntu 24.04, ssh authentication, public key, private key, ssh setup, faster ssh, developer workflow, command line, terminal, powershell, ssh client, security, ssh best practices
