Getting started with Nostr is not hard, but it is different enough from normal social apps that a lot of people get confused fast.
The biggest difference is this: your private key is your account.
There is no normal username-and-password recovery flow. There is no central support desk that can reset your identity. If you lose the private key, you lose control of that Nostr identity.
That sounds harsh, because it is. But it is also what gives Nostr its self-sovereign model.
Step 1: understand what you are creating
When you create a Nostr identity, you are really generating a cryptographic key pair:
- public key , your visible identity
- private key , the secret used to sign events
In human-friendly NIP-19 form, these are commonly represented as:
npub...for the public keynsec...for the private key
The public key is safe to share.
The private key is not.
Step 2: choose how you want to use Nostr
Most new users start in one of two ways:
Option A: use a Nostr client that creates a key for you
Many clients can generate a key pair during onboarding. This is simple, but you still need to export and back up the private key.
Option B: use a signer or browser extension
A signer keeps your key separate from the websites you use. On desktop, a NIP-07 extension such as Diogel is usually the safer option if you plan to use web clients.
That way, websites request signatures instead of asking you to paste your raw key into a page.
Step 3: back up your key immediately
This is the part beginners skip, then regret later.
As soon as you create or import a Nostr key:
- export the private key
- store it in a secure place
- verify that you can recover it later
Good backup options include:
- a trusted password manager
- encrypted offline storage
- secure physical backup for serious use
Bad options include:
- plain text notes in random cloud folders
- screenshots in your photo roll
- sending it to yourself in email or chat
Step 4: choose a client
Once you have a key or signer, you can use a client to actually interact with Nostr.
Common examples include:
The good part is that you are not locked into one client. If you do not like one, try another.
Step 5: connect to relays
Relays are the servers that accept and serve Nostr events. Most clients give you default relays to start with, which is fine for a beginner. Later on, you can get more selective about which relays you read from and publish to.

Step 6: secure your setup properly
A decent beginner setup looks like this:
- use a signer or extension on desktop
- back up your private key
- avoid pasting raw
nsecvalues into websites - keep your browser and extensions updated
- use more than one relay, but not a random junk pile of them

Common beginner mistakes
Treating Nostr like a normal account system
It is not. You are responsible for the key.
Not backing up the private key
This is the classic own goal.
Pasting raw keys into websites
This is one of the dumbest habits in the ecosystem. Use a signer where possible.
Assuming Nostr is private by default
It is not. Public posts are public, and relays can still observe plenty of activity.
Do you need to run your own infrastructure?
No.
You do not need to run your own relay or a self-hosted stack just to get started. That comes later, if you want more control.
Some advanced users prefer running their own services, dedicated signers, or home-server setups. That is fine, but it is not the starting requirement.
Conclusion
To get started with Nostr, you only need to understand a few core things:
- your private key is your account
- clients are interchangeable
- relays are infrastructure, not identity
- good key hygiene matters more than hype
If you get those basics right, the rest becomes much easier.
