How to Add user to access aws vps on ssh

• Access to your AWS Console
• Goto EC2
• Click Key Pairs on Network & Security on the left
• Create Key Pair, for example: support

• after you click the “create key pair” button, you will shown a download window for this pem file, keep this file secure because we cannot download again the same pem file.
• type these command to make it secure

sudo chmod 400 support.pem
ssh-keygen -y -f support.pem

• using ssh-keygen will encrypt the RSA, copy it to ssh file on aws vps (remember to copy the result on secure files)
• goto your vps

sudo adduser support --disabled-password
sudo su - support
mkdir .ssh
chmod 700 .ssh
touch .ssh/authorized_keys
chmod 600 .ssh/authorized_keys
nano .ssh/authorized_keys

• paste the “ssh-rsa” on this file
• you can try to access using this command

ssh -i "support.pem" support@[your aws server]
