Thanks much

this Help me a lot sir!

5 years and still amazing. ♥

Nice tutorial but still does not work...

really appreciated your video ....very helpful

Thank you sir. That was clear & very useful.

Nicely explained. Thank you.

wow you are so amazing at keeping things easy to follow, successfull first try!

Thank you for this video! The way you explained the pub key process finally clicked with me, after I spent yesterday reading documentation and getting it wrong.

Awesomely explained...ty

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!

Very clear explanations, thanks so much

I was waiting for this

Great video great simple explanation! It made my day, many thanks!

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!

great explanation

Gracias. Muy bien, excelente. Me aclaraste mucho. En Windows también se debe usar scp para copiar el archivo de la llave pública a la máquina remota.

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

this was awesome !!!!

It was very useful to me. Thank you so much.

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 :)

Very nice !!

what a good video!!! well explained

its work arigato

Nice Tutorial. Correct me when I'm wrong, I usually use the command "ssh-copy-id [email protected]" to do pretty the same thing.

What would you do if need the ability to have multiple machines to be able to SSH in to this device?

I immediately subscribed your channel .

I don't mean to be a stickler, but public key authentication isn't any more secure than password-based authentication. Keys aren't susceptible to capture by keyloggers, however, they introduce the risk of Trust On First Use on which they rely. Not a fair trade off.

The only truly secure method for SSH is to use certificate-based authentication which validates both the user and the host. You can enhance even that with two-factor authentication or other additional methods.

thanks for posting!

That's amzaing tutorial. Thank you so much!

thx so much

Thank you so much for this tutorial! Simple and well explained with all neccecary details!

stupid video just delete it is unusefull

b is a block size of 4MB

You are goated man!

How can I log in with SSH but as sudo directly ? Without asking for passwords or anything like that but be secure?

so if i have to use the password, what's the password it should be?

Just stumbled upon this video. Nicely done and perfectly explained. Thank you.

I keep finding your videos. They are are so good. Thank you.

Nice and clear, Thank you

I created ssh key and uploaded to my VPS, set chmod and still I am asked for a password, any idea why ?

Hi Corey, can you explain what happens to the authorised_key file when more than 1 person access the server using this method?

i need to login to many servers. Do i use the same public key and the same private key ?

thank you so much u r a great man

well explained, 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 ~
