Linux/Mac Tutorial: SSH Key-Based Authentication - How to SSH Without a Password

In this Linux/Mac terminal tutorial, we will be learning how to configure ssh keys so that we can login to our servers without a password. Not only is this more convenient, but it is also more secure. This also allows us to write automated scripts to talk to our servers without the need of putting in passwords constantly. Let's get started.

Well Explained. As a developer, it was bit difficult to understand others tutorial. Keep up the good work.

[chetansharma]

You have this special quality to explain things with simplicity.. Be it git or linux or python. I just enjoy your videos. A massive yes to your videos because you show hands on and not just theory. Awesome beyond Awesomeness

[kalyanhr]

Simple, Clear and Short video about SSH. Just just nailed it. Awesome job!!

[IcarianVX]

FINALLY - I have been messing with opening a dynamic tunnel from a linux machine TO a Mac for hours now. This tutorial (while backwards) was what I needed. Thanks Corey.

The way I remember is that the public key is like the lock on the door that everyone can try their private keys on, but only your private key will actually open the lock.
Copying the Public key is just installing the lock on the door on the server, that only your private key can open.
Great video btw!

[baldmike]

This one's the winner! Great video, very helpful, thank you.

[pauloferreira]

Extremely clean and direct information. This soluton worked for me at the first trial! Thanks for taking the time to do this video.

[BlancheNuit]

I''ve looked 4-5 videos on how to do that, maybe I'm dumb asf but none helped me.
Your video was crystal clear and it instantly worked, thanks

[randmssolutions]

As always, Corey explained the usage in a manner that is easily understood. I was stumped by the official SSH documentation because it doesn't clearly indicate which machine to copy the public key over to. Thank you Corey.

[kmontoya]

The quality and execution of this is so spot on to a tee - even 5 years old, this is golden content, thank you so much!

[geoptus]

This is by far the best and clearest explanation of how to implement k-b-a.
I have used keys for a while but never fully understood the details.
Thanks for this great tutorial Corey

[mamusthafa]

Short and sweet. I understood very clearly. awesome teacher. Waiting for more videos like this...

[ayan]

Amazing tutorial. Concise and to-the-point!

[bcross]

Thanks for this video, way more practical and informative than the others I found!

[muijnckj]

Finally a simple tutorial, it's not all that hard you know... Thank you!!

[w.schobel]

As always: Perfect explained. Great vid !

[ohtobetiramisu]

Holy shit thank you, I was trying to ssh into my ubuntu server through windows 11 and I knew it was way simpler than I was putting it out to be. Great and easy tutorial :)

[mattiylen]

Genuinely, very clear demonstration, rarely one can find as perfect as this

[skyhackerfpv]

Yes! It makes sense to me now. Public key goes on the remote server in the authorized_keys file, it was so helpful to see this being done. THANK YOU!

Great tuturial! Works on Windows to Linux too. If you use powershell the commands will be the same, just you have to type out your home directory manually when doing the scp instead of ~
