What are SSH keys

SSH keys are a pair of files that let you sign in to a server without a password. The public key goes on the server; the private key stays on your machine. The server lets you in only if you can prove you hold the private one.

The server sends a challenge, your computer signs it with the private key, the server checks the signature with the public key and lets you in Your laptop Private keynever leaves this file The server Public keyin authorized_keys 1. prove it is you: sign this 2. signature (not the key) 3. checked, you are in Nothing secret crosses the network. A stolen public key opens nothing.
The server holds the lock, you hold the key. Only a signature travels.

Make a pair

One command makes both files, and they land in ~/.ssh/. Ed25519 is the default type of current OpenSSH.

your laptop
$ ssh-keygen -t ed25519 -C "you@laptop"
Enter passphrase (empty for no passphrase):
Your public key has been saved in ~/.ssh/id_ed25519.pub
$ cat ~/.ssh/id_ed25519.pub
ssh-ed25519 AAAA… you@laptop
$ ssh [email protected]
signed in, no password asked

If it leaksAnyone holding it can sign in as youNothing happens

To put the public key on a server that still takes a password, run ssh-copy-id [email protected]. It appends your key to authorized_keys on the server; after that, turn passwords off.

Add a passphrase when ssh-keygen asks. It locks the private file, so a copy of the file alone is useless. The price: a lost passphrase cannot be recovered; you make a new key.

Why keys beat passwords

A password can be guessed, and bots try common ones all day against any server with an open SSH port. A key cannot be guessed: it is a long random number. A key also lets a program sign in. An AI agent that runs commands on your server uses a key, not a password you would have to paste into a chat.

Do you need them?

Use keys when

  • You sign in to a server. Any VPS or cloud computer.
  • You push code to Git. GitHub and GitLab accept your public key.
  • A program signs in for you. Deploy scripts and agents.

You can skip them when

  • You never leave the browser. A web terminal signs you in itself.
  • The host gives no SSH. Then there is no door to lock.

SSH keys in Uno

  • Login: computers take SSH keys only; passwords are not accepted.
  • Reuse: you can save a key once on your account and reuse it for new computers.
  • Connect: Uno gives you the ready ssh command for each computer; copy it as it is.
  • Record: every sign-in is a row in your access log, which has filters: All, You, AI agents, Uno, SSH.

What to know before you connect

  • Asleep: an SSH connection does not wake a sleeping computer; wake it first from Uno Work or the console.

What a server on Uno adds

The same SSH you know, plus a computer that wakes with its memory and an agent that can set it up.

It sleeps when idle and keeps its memory

With nothing to do for 10 minutes it falls asleep with every program still in memory. A visitor, a bot message or you wake it. Every hour asleep earns you a boost.

An AI agent sets it up for you

Tell Uno what you need in a chat. It installs, configures and starts it on your computer, and you watch every command it runs. Or bring Claude Code or Codex with your own subscription.

Fast where it counts

NVMe disks and DDR5 with error correction (ECC). On 16 vCPU an Uno computer scores like a MacBook Air M4 in Geekbench 6: a second MacBook in the cloud for $70 a month.

A clean address of your own

Traffic can leave through a static address of a regular internet provider in one of 8 countries, used only by your account. Fewer captchas for your agent's browser.

Nothing happens unseen

Every time Uno itself touches your computer, it goes to your access log: who, when and why.

Questions

Which type should I choose?
Ed25519. It is the default of current OpenSSH, the keys are short and every modern server accepts them.
Can I use one key on several servers?
Yes. Put the same public key on each. Many people keep one key per laptop, so a lost laptop means removing one key everywhere.
I lost my private key. Now what?
Make a new pair and add the new public key to the server. If your old key was the only way in, use the web terminal or the host's console to add it.
Is it safe to paste a public key into a chat or a form?
Yes, that is its job. Never paste the file without .pub.
