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.
