In this video we are going to learn Password less authentication in Ubuntu 22.04 LTS AWS EC2 and connect to user without Password.
Requirements
- AWS Account
- Amazon EC2 Ubuntu 22.04
- A user with the sudo privilege command
- Atleast 2 user (to connect password less)
Step #1:Create new user in Ubuntu
Lets create new user in server
sudo adduser devopshint
now navigate the devopshint user
su - devopshint
Step #2:Then give some privileged using below command
Run the below command to give privileged:
sudo visudo
go to inside this file and add this line
devopshint ALL=(ALL) NOPASSWD:ALL

Login to devopshint using below command:
su - devopshint
Run the below command to connect node:
ssh ip_address ( ec2-public-ip)
Step #5:Remove password
To remove password run the below command
We need to generate ssh keygen
ssh-keygen
You need to inside .ssh:
cd .ssh
Now run the below command using private ip of your node:
ssh-copy-id devopshint@{ec2-public-ip}
Step #6:Lets connect to user without Password | Password less authentication in Ubuntu
Now lets connect to node to the server without password using below command:
ssh devopshint@ip_address
Conclusion:
