# Users

> Understanding user management in Nile Auth

Learn about user management concepts in Nile Auth, including how to create, update, and manage users and their sessions.

## User Model

The `User` model in Nile Auth defines the structure of a user object. It includes both basic and custom properties to meet the needs of your application.

```typescript theme={null}
interface User {
  id: string;
  email: string;
  name?: string | null;
  familyName?: string | null;
  givenName?: string | null;
  picture?: string | null;
  created: string;
  updated?: string;
  emailVerified?: string | null;
  tenants: { id: string }[];
}
```

## User Properties

### Basic Properties

* **Email**: The user's email address. This is true across all users of a database
* **Profile information**: Includes details like the user's name, contact info, and other relevant data, along with any tenants the user is associated.

## User Operations

### Creating Users

To create a new user, you can make a POST request to the `/users` endpoint.

```typescript theme={null}
const newUser = await nile.users.createUser({
  email: 'user@example.com',
  password: 'user1',
});
```

### Adding users

When a user is created, they are not automatically added to a tenant, unless `newTenant` is present. Users can only add other users to tenants of which they are a member. To add a user to a tenant, use `linkUser`

```typescript theme={null}
const user1 = await nile.users.createUser({
  email: 'user1@example.com',
  password: 'user1',
  newTenant: 'myTenant',
});
const user2 = await nile.users.createUser({
  email: 'user2@example.com',
  password: 'user2',
});
// make user1 and user2 part of the same tenant
const updated2 = await nile.tenants.addMember(user2.id);
```

### Updating Users

Because users are isolated to their own session, existing user update themselves via `PUT` method. A custom endpoint would need to be created in order for one user to update the information of another.

```typescript theme={null}
const updatedUser = await nile.users.updateSelf({ name: 'user1' });
```

### Deleting Users

Because user accounts are isolated, one user is unable to delete another. It is possible remove a user from a tenant from the built-in API. In order to to that, use `unlinkUser`

```typescript theme={null}
const unlinked = await nile.tenants.removeMember(user2.id);
```

## User Authentication

### Password-based Authentication

<Warning>
  Password-based authentication is not recommended for production applications.
  Use social authentication or other secure methods instead.
</Warning>

You can authenticate users using their email and password. After a successful login, a session token in for form of a JWT is returned. All other forms use a session token saved in the database.
For demonstration purposes, we are using the server-side methods. It would be rare to do this in a real application.

```typescript theme={null}
// Example password authentication - not recommended for production
const session = await nile.auth.login({
  email: 'user@example.com',
  password: 'password123',
});
```

### Social Authentication

Nile Auth also supports social authentication via OAuth providers such as Google or Facebook. In order to configure this, see [Single Sign On](/auth/singlesignon/google)

## User Sessions

A session is always within the context of a request. You can access session data using:

```typescript theme={null}
const session = await nile.auth.getSession();
```
