Detailed Description

This serves as the entry point to the authentication system.

In the future, it may also serve as the entry point to the authorization system.

If you are looking at this because you are working on an extension that creates its own login or signup page, then 1) you really shouldn't do that, 2) if you feel you absolutely have to, subclass AuthManagerSpecialPage or build it on the client side using the clientlogin or the createaccount API. Trying to call this class directly will very likely end up in security vulnerabilities or broken UX in edge cases.

If you are working on an extension that needs to integrate with the authentication system (e.g. by providing a new login method, or doing extra permission checks), you'll probably need to write an AuthenticationProvider.

If you want to create a "reserved" user programmatically, User::newSystemUser() might be what you are looking for. If you want to change user data, use User::changeAuthenticationData(). Code that is related to some SessionProvider or PrimaryAuthenticationProvider can create a (non-reserved) user by calling AuthManager::autoCreateUser(); it is then the provider's responsibility to ensure that the user can authenticate somehow (see especially PrimaryAuthenticationProvider::autoCreatedAccount()). If you are writing code that is not associated with such a provider and needs to create accounts programmatically for real users, you should rethink your architecture. There is no good way to do that as such code has no knowledge of what authentication methods are enabled on the wiki and cannot provide any means for users to access the accounts it would create.

The two main control flows when using this class are as follows:

Login, user creation or account linking code will call getAuthenticationRequests(), populate the requests with data (by using them to build a HTMLForm and have the user fill it, or by exposing a form specification via the API, so that the client can build it), and pass them to the appropriate begin* method. That will return either a success/failure response, or more requests to fill (either by building a form or by redirecting the user to some external provider which will send the data back), in which case they need to be submitted to the appropriate continue* method and that step has to be repeated until the response is a success or failure response. AuthManager will use the session to maintain internal state during the process.
Code doing an authentication data change will call getAuthenticationRequests(), select a single request, populate it, and pass it to allowsAuthenticationDataChange() and then changeAuthenticationData(). If the data change is user-initiated, the whole process needs to be preceded by a call to securitySensitiveOperationStatus() and aborted if that returns a non-OK status.

Member Function Documentation

◆ allowsAuthenticationDataChange()

MediaWiki\Auth\AuthManager::allowsAuthenticationDataChange	(	AuthenticationRequest	$req,
			$checkData = true )

Validate a change of authentication data (e.g.

passwords)

Parameters

AuthenticationRequest	$req
bool	$checkData	If false, $req hasn't been loaded from the submission so checks on user-submitted fields should be skipped. $req->username is considered user-submitted for this purpose, even if it cannot be changed via $req->loadFromSubmission.

Returns: Status

References $req, MediaWiki\Auth\AuthManager\getPrimaryAuthenticationProviders(), and MediaWiki\Auth\AuthManager\getSecondaryAuthenticationProviders().

Referenced by MediaWiki\Auth\AuthManager\getAuthenticationRequestsInternal().

◆ allowsPropertyChange()

MediaWiki\Auth\AuthManager::allowsPropertyChange ( $property )

Determine whether a user property should be allowed to be changed.

Supported properties are:

emailaddress
realname
nickname

Parameters

string $property

Returns: bool

Definition at line 2189 of file AuthManager.php.

References $property, MediaWiki\Auth\AuthManager\getPrimaryAuthenticationProviders(), and MediaWiki\Auth\AuthManager\getSecondaryAuthenticationProviders().

◆ autoCreateUser()

MediaWiki\Auth\AuthManager::autoCreateUser	(	User	$user,
			$source,
			$login = true )

Auto-create an account, and log into that account.

PrimaryAuthenticationProviders can invoke this method by returning a PASS from beginPrimaryAuthentication/continuePrimaryAuthentication with the username of a non-existing user. SessionProviders can invoke it by returning a SessionInfo with the username of a non-existing user from provideSessionInfo(). Calling this method explicitly (e.g. from a maintenance script) is also fine.

Parameters

User	$user	User to auto-create
string	$source	What caused the auto-creation? This must be the ID of a PrimaryAuthenticationProvider or the constant self::AUTOCREATE_SOURCE_SESSION.
bool	$login	Whether to also log the user in

Returns: Status Good if user was created, Ok if user already existed, otherwise Fatal

◆ beginAccountCreation()

MediaWiki\Auth\AuthManager::beginAccountCreation	(	User	$creator,
		array	$reqs,
			$returnToUrl )

Start an account creation flow.

In addition to the AuthenticationRequests returned by $this->getAuthenticationRequests(), a client might include a CreateFromLoginAuthenticationRequest from a previous login attempt. If $createFromLoginAuthenticationRequest->hasPrimaryStateForAction( AuthManager::ACTION_CREATE ) returns true, any AuthenticationRequest::PRIMARY_REQUIRED requests should be omitted. If the CreateFromLoginAuthenticationRequest has a username set, that username must be used for all other requests.

Parameters

User	$creator	User doing the account creation
AuthenticationRequest[]	$reqs
string	$returnToUrl	Url that REDIRECT responses should eventually return to.

Returns: AuthenticationResponse

◆ securitySensitiveOperationStatus()

MediaWiki\Auth\AuthManager::securitySensitiveOperationStatus ( $operation )

Whether security-sensitive operations should proceed.

A "security-sensitive operation" is something like a password or email change, that would normally have a "reenter your password to confirm" box if we only supported password-based authentication.
