How can I set up password-less SSH login?
I am using ssh to connect to a remote server. I am prompted to provide a password each time, but I recall being able to set up a sort of authentication key, so that passwords were not required.
However, it has been ages, and I have forgotten just about everything about it, except the word “key”. One of those things you set up and forget, and I never quite understood it to begin with.
How is it done?
Here is Solutions:
We have many solutions to this problem, But we recommend you to use the first solution because it is tested & true solution that will 100% work for you.
The answer you are looking for is here. Following is the excerpt from it :
Run the following command to create an SSH key pair. You can leave the passphrase blank if you do not wish to “unlock” your key each time you use it:
ssh-keygen -t rsa
The output will be similar to this
Generating public/private rsa key pair. Enter file in which to save the key (/home/a/.ssh/id_rsa): Created directory '/home/a/.ssh'. Enter passphrase (empty for no passphrase): Enter same passphrase again: Your identification has been saved in /home/a/.ssh/id_rsa. Your public key has been saved in /home/a/.ssh/id_rsa.pub. The key fingerprint is: 3e:4f:05:79:3a:9f:96:7c:3b:ad:e9:58:37:bc:37:e4 [email protected]
After copying the SSH keys you can log into your machine without a password.
Note: Use and implement solution 1 because this method fully tested our system.
Thank you 🙂
