  To transfer a folder without being asked for a password each time with scp , you should set up SSH key-based authentication between your local machine and the remote server. Here’s how 👇 Step 1: Generate SSH Key (on your local machine) type below command  ssh-keygen -t rsa Press Enter for default file location ( ~/.ssh/id_rsa ). If you want, set a passphrase (or leave it empty for no password). Step 2: Copy the Public Key to Remote Server ssh-copy-id root@1 92.168.0.201 or manually: cat ~/.ssh/id_rsa.pub | ssh root@ 1 92.1688.0.201 "mkdir -p ~/.ssh && cat >> ~/.ssh/authorized_keys && chmod 600 ~/.ssh/authorized_keys && chmod 700 ~/.ssh" 👉 Enter the password once here. After this, the key will be stored in ~/.ssh/authorized_keys on the remote server. Step 3: Test Passwordless Login ssh root@192.168.0.201  If it logs in without asking for a password — you're done.  Step 4: Transfer Folder with scp (No Password Now) scp -r tes...
