This is a pretty huge update with a lot of new features.

New Features

Support for `linux/arm64`

With the release of v0.17.0, Rauthy's container images are now multi-platform.

Both a linux/amd64 and a linux/arm64 are supported. This means you can "just use it" now on Raspberry Pi and
others, or on Ampere architecture from Cloud providers without the need to compile it yourself.

Events and Auditing

Rauthy now produces events in all different kinds of situations. These can be used for auditing, monitoring, and so on.
You can configure quite a lot for them in the new EVENTS / AUDIT section in the
Rauthy Config.

These events are persisted in the database, and they can be fetched in real time via a new Server Sent Events(SSE)
endpoint /auth/v1/events/stream. There is a new UI component in the Admin UI that uses the same events stream.
In case of a HA deployment, Rauthy will use one additional DB connection (all the time) from the connection pool
to distribute these events via pg listen / notify to the other members. This makes a much simpler deployment and
there is no real need to deploy additional resources like Nats or something like that. This keeps the setup easier
and therefore more fault-tolerant.

You should at least set EVENT_EMAIL now, if you update from an older version.

Slack and Matrix Integrations

The new Events can be sent to a Slack Webhook or Matrix Server.

The Slack integration uses the simple (legacy) Slack Webhooks and can be configured with EVENT_SLACK_WEBHOOK:

# The Webhook for Slack Notifications.
# If left empty, no messages will be sent to Slack.
#EVENT_SLACK_WEBHOOK=

The Matrix integration can connect to a Matrix server and room. This setup requires you to provide a few more
variables:

# Matrix variables for event notifications.
# `EVENT_MATRIX_USER_ID` and `EVENT_MATRIX_ROOM_ID` are mandatory.
# Depending on your Matrix setup, additionally one of
# `EVENT_MATRIX_ACCESS_TOKEN` or `EVENT_MATRIX_USER_PASSWORD` is needed.
# If you log in to Matrix with User + Password, you may use `EVENT_MATRIX_USER_PASSWORD`.
# If you log in via OIDC SSO (or just want to use a session token you can revoke),
# you should provide `EVENT_MATRIX_ACCESS_TOKEN`.
# If both are given, the `EVENT_MATRIX_ACCESS_TOKEN` will be preferred.
#
# If left empty, no messages will be sent to Slack.
# Format: `@<user_id>:<server address>`
#EVENT_MATRIX_USER_ID=
# Format: `!<random string>:<server address>`
#EVENT_MATRIX_ROOM_ID=
#EVENT_MATRIX_ACCESS_TOKEN=
#EVENT_MATRIX_USER_PASSWORD=
# Optional path to a PEM Root CA certificate file for the Matrix client.
#EVENT_MATRIX_ROOT_CA_PATH=tls/root.cert.pem
# May be set to disable the TLS validation for the Matrix client.
# default: false
#EVENT_MATRIX_DANGER_DISABLE_TLS_VALIDATION=false

You can configure the minimum event level which would trigger it to be sent:

# The notification level for events. Works the same way as a logging level. For instance:
# 'notice' means send out a notifications for all events with the info level or higher.
# Possible values:
# - info
# - notice
# - warning
# - critical
#
# default: 'warning'
EVENT_NOTIFY_LEVEL_EMAIL=warning
# default: 'notice'
EVENT_NOTIFY_LEVEL_MATRIX=notice
# default: 'notice'
EVENT_NOTIFY_LEVEL_SLACK=notice

Increasing Login Timeouts

Up until version 0.16, a failed login would extend the time the client needed to wait for the result
artificially until it ended up in the region of the median time to log in successfully.
This was already a good thing to do to prevent username enumeration.
However, this has been improved a lot now.

When a client does too many invalid logins, the time he needs to wait until he may do another try
increases with each failed attempt. The important thing here is, that this is not bound to a user,
but instead to the clients IP.
This makes sure, that an attacker cannot just lock a users account by doing invalid logins and therefore
kind of DoS the user. Additionally, Rauthy can detect Brute-Force or DoS attempts independently of
a users account.

There are certain thresholds at 7, 10, 15, 20, 25 invalid logins, when a clients IP will get fully
blacklisted (explained below) for a certain amount of time. This is a good DoS and even DDoS prevention.

Ip Blacklist Middleware

This is a new HTTP middleware which checks the clients IP against an internal blacklist.

This middleware is the very first thing that is being executed and just returns an HTML page
to a blacklisted client with the information about the blacklisting and the expiry.
This blacklist is in-memory only to be as fast as possible to actually be able to handle brute
force and DoS attacks in the best way possible while consuming the least amount of resources
to do this.

Currently, IP's may get blacklisted in two ways:

Automatically when exceeding the above-mentioned thresholds for invalid logins in a row
Manually via the Admin UI

Blacklisted IP's always have an expiry and will get removed from the blacklist automatically.
Both actions will trigger one of the new Rauthy Events and send out notifications.

JWKS Auto-Rotate Scheduler

This is a simple new cron job which rotates the JSON Web Key Set (JWKS) automatically for
enhanced security, just in case one of the keys may get leaked at some point.

By default, it runs every first day of the month. This can be adjusted in the config:

# JWKS auto rotate cronjob. This will (by default) rotate all JWKs every
# 1. day of the month. If you need smaller intervals, you may adjust this
# value. For security reasons, you cannot fully disable it.
# In a HA deployment, this job will only be executed on the current cache
# leader at that time.
# Format: "sec min hour day_of_month month day_of_week year"
# default: "0 30 3 1 * * *"
JWK_AUTOROTATE_CRON="0 30 3 1 * * *"

Fully Reworked Authentication Middleware

The authentication and authorization system has been fully reworked and improved.

The new middleware and way of checking the client's access rights in each endpoint is way
less error-prone than before. The whole process has been much simplified which indirectly
improves the security:

CSRF Tokens are now checked automatically if the request method is any other than a GET
Bearer Tokens are not allowed anymore to access the Admin API
A new ApiKey token type has been added (explained below)
Only a single authn/authz struct is needed to validate each endpoint
The old permission extractor middleware was removed which also increases the performance a bit

New API-Key Type

This new API-Key type may be used, if you need to access Rauthy API from other applications.

Beforehand, you needed to create a "user" for an application, if you wanted to access the API,
which is kind of counter-intuitive and cumbersome.
These new API-Keys can be used to handle this task now. These are static keys with an
optional expiry date and fine-grained access rights. You should only give them permissions
to the resources you actually need to further improve your backend security.

They can be easily created, configured and revoked / deleted in the Admin UI at any time.

IMPORTANt: The API now cannot be accessed anymore with Bearer tokens! If you used this
method until now, you need to switch to the new API Keys

OIDC Client FORCE_MFA feature

In the configuration for each individual OIDC client, you can find a new FORCE MFA switch.
It this new option is activated for a client, it will only issue authentication codes for
those users, that have at least one Passkey registered.
This makes it possible to force MFA for all your different applications from Rauthy directly
without the need to check for the amr claim in the ID token and do or configure all of
this manually downstream. Most of the time, you may not even have control over the client
itself, and you are basically screwed, if the client does not have its own "force mfa integration".

CAUTION: This mentioned in the UI as well, but when you check this new force mfa option,
it can only force MFA for the authorization_code flow of course! If you use other flows,
there just is no MFA that could be checked / forced.

Rauthy Version Checker

Since we do have an Events system now, there is a new scheduled cron job, which checks the
latest available Rauthy Version.

This Job runs once every 8 hours and does a single poll to the Github Releases API. It looks
for the latest available Rauthy Version that is not a prerelease or anything unstable.
If it finds a version higher than the currently running one, a new Event will be generated.
Additionally,
you will see the current Rauthy Version in the UI now and a small indicator just next to it,
if there is a stable update available.

Bugfixes

A User may have not been updated correctly in the cache when the E-Mail was changed.
8d9cdce
With v0.16, it was possible to not be able to switch back to a password account type from passkey,
when it was a password account before already which did update its password in the past and therefore
would have entries in the DB for last_recent_passwords if you had the password policy correctly.
7a965a2
When you were using a password manager that filled out the username 'again' in the login form,
after the additional password request input showed up, it could reset the form on some browser.

Removed

The ADMIN_ACCESS_SESSION_ONLY config variable was removed. This was obsolete now with
the introduction of the new ApiKey type.
