37 * This serves as the entry point to the authentication system.
39 * In the future, it may also serve as the entry point to the authorization
42 * If you are looking at this because you are working on an extension that creates its own
43 * login or signup page, then 1) you really shouldn't do that, 2) if you feel you absolutely
44 * have to, subclass AuthManagerSpecialPage or build it on the client side using the clientlogin
45 * or the createaccount API. Trying to call this class directly will very likely end up in
46 * security vulnerabilities or broken UX in edge cases.
48 * If you are working on an extension that needs to integrate with the authentication system
49 * (e.g. by providing a new login method, or doing extra permission checks), you'll probably
50 * need to write an AuthenticationProvider.
52 * If you want to create a "reserved" user programmatically, User::newSystemUser() might be what
53 * you are looking for. If you want to change user data, use User::changeAuthenticationData().
54 * Code that is related to some SessionProvider or PrimaryAuthenticationProvider can
55 * create a (non-reserved) user by calling AuthManager::autoCreateUser(); it is then the provider's
56 * responsibility to ensure that the user can authenticate somehow (see especially
57 * PrimaryAuthenticationProvider::autoCreatedAccount()). The same functionality can also be used
58 * from Maintenance scripts such as createAndPromote.php.
59 * If you are writing code that is not associated with such a provider and needs to create accounts
60 * programmatically for real users, you should rethink your architecture. There is no good way to
61 * do that as such code has no knowledge of what authentication methods are enabled on the wiki and
62 * cannot provide any means for users to access the accounts it would create.
64 * The two main control flows when using this class are as follows:
65 * * Login, user creation or account linking code will call getAuthenticationRequests(), populate
66 * the requests with data (by using them to build a HTMLForm and have the user fill it, or by
67 * exposing a form specification via the API, so that the client can build it), and pass them to
68 * the appropriate begin* method. That will return either a success/failure response, or more
69 * requests to fill (either by building a form or by redirecting the user to some external
70 * provider which will send the data back), in which case they need to be submitted to the
71 * appropriate continue* method and that step has to be repeated until the response is a success
72 * or failure response. AuthManager will use the session to maintain internal state during the
74 * * Code doing an authentication data change will call getAuthenticationRequests(), select
75 * a single request, populate it, and pass it to allowsAuthenticationDataChange() and then
76 * changeAuthenticationData(). If the data change is user-initiated, the whole process needs
77 * to be preceded by a call to securitySensitiveOperationStatus() and aborted if that returns
82 * @see https://www.mediawiki.org/wiki/Manual:SessionManager_and_AuthManager
