- Minimum Supported Rust Version (MSRV): 1.57
Identity management for Actix Web.
`actix-identity` can be used to track identity of a user across multiple requests. It is built on top of HTTP sessions, via [`actix-session`](https://docs.rs/actix-session).
## Getting started
To start using identity management in your Actix Web application you must register [`IdentityMiddleware`] and `SessionMiddleware` as middleware on your `App`:
```rust
use actix_web::{cookie::Key, App, HttpServer, HttpResponse};
use actix_identity::IdentityMiddleware;
use actix_session::{storage::RedisSessionStore, SessionMiddleware};
#[actix_web::main]
async fn main() {
// When using `Key::generate()` it is important to initialize outside of the
// `HttpServer::new` closure. When deployed the secret key should be read from a
// configuration file or environment variables.
let secret_key = Key::generate();
let redis_store = RedisSessionStore::new("redis://127.0.0.1:6379")
.await
.unwrap();
HttpServer::new(move || {
App::new()
// Install the identity framework first.
.wrap(IdentityMiddleware::default())
// The identity system is built on top of sessions. You must install the session
// middleware to leverage `actix-identity`. The session middleware must be mounted
// AFTER the identity middleware: `actix-web` invokes middleware in the OPPOSITE
// order of registration when it receives an incoming request.
.wrap(SessionMiddleware::new(
redis_store.clone(),
secret_key.clone()
))
// Your request handlers [...]
})
}
```
User identities can be created, accessed and destroyed using the [`Identity`] extractor in your request handlers:
```rust
use actix_web::{get, post, HttpResponse, Responder, HttpRequest, HttpMessage};
use actix_identity::Identity;
use actix_session::storage::RedisSessionStore;
#[get("/")]
async fn index(user: Option<Identity>) -> impl Responder {
if let Some(user) = user {
format!("Welcome! {}", user.id().unwrap())
} else {
"Welcome Anonymous!".to_owned()
}
}
#[post("/login")]
async fn login(request: HttpRequest) -> impl Responder {
// Some kind of authentication should happen here
// e.g. password-based, biometric, etc.
// [...]
// attach a verified user identity to the active session
Identity::login(&request.extensions(), "User1".into()).unwrap();
HttpResponse::Ok()
}
#[post("/logout")]
async fn logout(user: Identity) -> impl Responder {
user.logout();
HttpResponse::Ok()
}
```
## Advanced configuration
By default, `actix-identity` does not automatically log out users. You can change this behaviour by customising the configuration for [`IdentityMiddleware`] via [`IdentityMiddleware::builder`].
In particular, you can automatically log out users who:
- have been inactive for a while (see [`IdentityMiddlewareBuilder::visit_deadline`];
- logged in too long ago (see [`IdentityMiddlewareBuilder::login_deadline`]).
[`IdentityMiddlewareBuilder::visit_deadline`]: config::IdentityMiddlewareBuilder::visit_deadline

Session management for Actix Web.
The HTTP protocol, at a first glance, is stateless: the client sends a request, the server parses its content, performs some processing and returns a response. The outcome is only influenced by the provided inputs (i.e. the request content) and whatever state the server queries while performing its processing.
Stateless systems are easier to reason about, but they are not quite as powerful as we need them to be - e.g. how do you authenticate a user? The user would be forced to authenticate **for every single request**. That is, for example, how 'Basic' Authentication works. While it may work for a machine user (i.e. an API client), it is impractical for a person—you do not want a login prompt on every single page you navigate to!
There is a solution - **sessions**. Using sessions the server can attach state to a set of requests coming from the same client. They are built on top of cookies - the server sets a cookie in the HTTP response (`Set-Cookie` header), the client (e.g. the browser) will store the cookie and play it back to the server when sending new requests (using the `Cookie` header).
We refer to the cookie used for sessions as a **session cookie**. Its content is called **session key** (or **session ID**), while the state attached to the session is referred to as **session state**.
`actix-session` provides an easy-to-use framework to manage sessions in applications built on top of Actix Web. [`SessionMiddleware`] is the middleware underpinning the functionality provided by `actix-session`; it takes care of all the session cookie handling and instructs the **storage backend** to create/delete/update the session state based on the operations performed against the active [`Session`].
`actix-session` provides some built-in storage backends: ([`CookieSessionStore`], [`RedisSessionStore`], and [`RedisActorSessionStore`]) - you can create a custom storage backend by implementing the [`SessionStore`] trait.
Further reading on sessions:
- [RFC 6265](https://datatracker.ietf.org/doc/html/rfc6265);
- [OWASP's session management cheat-sheet](https://cheatsheetseries.owasp.org/cheatsheets/Session_Management_Cheat_Sheet.html).
## Getting started
To start using sessions in your Actix Web application you must register [`SessionMiddleware`] as a middleware on your `App`:
```rust
use actix_web::{web, App, HttpServer, HttpResponse, Error};
use actix_session::{Session, SessionMiddleware, storage::RedisActorSessionStore};
use actix_web::cookie::Key;
#[actix_web::main]
async fn main() -> std::io::Result<()> {
// When using `Key::generate()` it is important to initialize outside of the
// `HttpServer::new` closure. When deployed the secret key should be read from a
// configuration file or environment variables.
let secret_key = Key::generate();
let redis_store = RedisSessionStore::new("redis://127.0.0.1:6379")
.await
.unwrap();
HttpServer::new(move ||
App::new()
// Add session management to your application using Redis for session state storage
.wrap(
SessionMiddleware::new(
redis_store.clone(),
secret_key.clone(),
)
)
.default_service(web::to(|| HttpResponse::Ok())))
.bind(("127.0.0.1", 8080))?
.run()
.await
}
```
The session state can be accessed and modified by your request handlers using the [`Session`] extractor. Note that this doesn't work in the stream of a streaming response.
```rust
use actix_web::Error;
use actix_session::Session;
fn index(session: Session) -> Result<&'static str, Error> {
// access the session state
if let Some(count) = session.get::<i32>("counter")? {
println!("SESSION value: {}", count);
// modify the session state
session.insert("counter", count + 1)?;
} else {
session.insert("counter", 1)?;
}
Ok("Welcome!")
}
```
## Choosing A Backend
By default, `actix-session` does not provide any storage backend to retrieve and save the state attached to your sessions. You can enable:
- a purely cookie-based "backend", [`CookieSessionStore`], using the `cookie-session` feature flag.
```toml
[dependencies]
# ...
actix-session = { version = "...", features = ["cookie-session"] }
```
- a Redis-based backend via [`actix-redis`](https://docs.rs/actix-redis), [`RedisActorSessionStore`], using the `redis-actor-session` feature flag.
```toml
[dependencies]
# ...
actix-session = { version = "...", features = ["redis-actor-session"] }
```
- a Redis-based backend via [`redis-rs`](https://docs.rs/redis-rs), [`RedisSessionStore`], using the `redis-rs-session` feature flag.
```toml
[dependencies]
# ...
actix-session = { version = "...", features = ["redis-rs-session"] }
```
Add the `redis-rs-tls-session` feature flag if you want to connect to Redis using a secured connection:
```toml
[dependencies]
# ...
actix-session = { version = "...", features = ["redis-rs-session", "redis-rs-tls-session"] }
```
You can implement your own session storage backend using the [`SessionStore`] trait.

The session state can be accessed and modified by your request handlers using the [`Session`]
extractor. Note that this doesn't work in the stream of a streaming response.
```no_run
use actix_web::Error;
use actix_session::Session;
fn index(session: Session) -> Result<&'static str, Error> {
// access the session state
if let Some(count) = session.get::<i32>("counter")? {
println!("SESSION value: {}", count);
// modify the session state
session.insert("counter", count + 1)?;
} else {
session.insert("counter", 1)?;
}
Ok("Welcome!")
}
```
# Choosing A Backend
By default, `actix-session` does not provide any storage backend to retrieve and save the state
attached to your sessions. You can enable:
- a purely cookie-based "backend", [`CookieSessionStore`], using the `cookie-session` feature
flag.
```toml
[dependencies]
# ...
actix-session = { version = "...", features = ["cookie-session"] }
```
- a Redis-based backend via [`actix-redis`](https://docs.rs/actix-redis),
[`RedisActorSessionStore`], using the `redis-actor-session` feature flag.
```toml
[dependencies]
# ...
actix-session = { version = "...", features = ["redis-actor-session"] }
```
- a Redis-based backend via [`redis-rs`](https://docs.rs/redis-rs), [`RedisSessionStore`], using
the `redis-rs-session` feature flag.
```toml
[dependencies]
# ...
actix-session = { version = "...", features = ["redis-rs-session"] }
```
Add the `redis-rs-tls-session` feature flag if you want to connect to Redis using a secured
connection:
```toml
[dependencies]
# ...
actix-session = { version = "...", features = ["redis-rs-session", "redis-rs-tls-session"] }
```
You can implement your own session storage backend using the [`SessionStore`] trait.
[`SessionStore`]: storage::SessionStore
[`CookieSessionStore`]: storage::CookieSessionStore
[`RedisSessionStore`]: storage::RedisSessionStore
[`RedisActorSessionStore`]: storage::RedisActorSessionStore
