It is possible to ssh into your Linux VPS without having to use a password.
Here are the steps:
- Create ssh key if you dont have one already
- Add the public ssh to the remote servers
authorized_keyslist
If you already have an ssh key skip to step 2
1 Create ssh key
Fire up the terminal and first go to your .ssh folder on your personal computer.
cd ~/.ssh
Then type (to create the ssh key)
ssh-keygen -t rsa -b 4096 -C "your@email.com"
Follow the prompts
- push enter for each question to accept the defaults
- it will create a prive and public ssh key called
id_rsaandid_rsa.pub - do not enter a passwords
It will look like this:
Generating public/private rsa key pair.
Enter file in which to save the key (/home/mannuel/.ssh/id_rsa): id_rsa_test
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in id_rsa
Your public key has been saved in id_rsa.pub
The key fingerprint is:
SHA256:52n1XC/4hSWgwC8gqK0Ld0ym/fb3BBXbhHypgmQFUHI your@email.com
The key's randomart image is:
+---[RSA 4096]----+
| ooEo...... |
| . +o o=o |
| . . .oo. +o. |
| o . ..o.o.. |
|. . o S =.. . o|
| . * + + + =.|
|o o + + o = o|
|.o . .. ... . o |
|. ..... .. . |
+----[SHA256]-----+
2 Add key to authorized_keys list
cat ~/.ssh/id_rsa.pub | ssh yourUsername@000.000.00.00 'cat >> ~/.ssh/authorized_keys'
you will be prompted to enter your VPS password given for yourUsername.
cat ~/.ssh/id_rsa.pub | ssh yourUsername@000.000.00.00 'cat >> ~/.ssh/authorized_keys'
yourUsername@000.000.00.00's password:
Jobs done, you should be able to ssh into VPS without entering a password.
