Most software keeps track of users by giving them a username and password. This gives the service total control over their users, allowing them to ban them at any time, or sell their activity.

On Nostr, you control your own identity and social data, through the magic of crytography. The basic idea is that you have a public key, which acts as your user id, and a private key which allows you to authenticate any message you send.

It's very important to keep private keys safe, but this can sometimes be confusing for newcomers. This is why flotilla supports remote signer login. These services can store your keys securely for you, giving you access using a username and password.
