Detailed Description

A secondary provider mostly acts when the submitted authentication data has already been associated to a MediaWiki user account.

For login, a secondary provider performs additional authentication steps after a PrimaryAuthenticationProvider has identified which MediaWiki user is trying to log in. For example, it might implement a password reset, request the second factor for two-factor auth, or prevent the login if the account is blocked.

For account creation, a secondary provider performs optional extra steps after a PrimaryAuthenticationProvider has created the user; for example, it can collect further user information such as a biography.

(For account linking, secondary providers are not involved.)

This interface also provides methods for changing authentication data such as a second-factor token, and callbacks that are invoked after login / account creation succeeded or failed.

Member Function Documentation

◆ autoCreatedAccount()

MediaWiki\Auth\SecondaryAuthenticationProvider::autoCreatedAccount	(		$user,
			$source )

Post-auto-creation callback.

Parameters

User	$user	User being created (has been added to the database now). This may become a "UserValue" in the future, or User may be refactored into such.
string	$source	The source of the auto-creation passed to AuthManager::autoCreateUser().

Implemented in MediaWiki\Auth\AbstractSecondaryAuthenticationProvider.

◆ beginSecondaryAccountCreation()

MediaWiki\Auth\SecondaryAuthenticationProvider::beginSecondaryAccountCreation	(		$user,
			$creator,
		array	$reqs )

Start an account creation flow.

Note: There is no guarantee this will be called in a successful account creation process as the user can just abandon the process at any time after the primary provider has issued a PASS and still have a valid account. Be prepared to handle any database inconsistencies that result from this or continueSecondaryAccountCreation() not being called.

Parameters

User	$user	User being created (has been added to the database). This may become a "UserValue" in the future, or User may be refactored into such.
User	$creator	User doing the creation. This may become a "UserValue" in the future, or User may be refactored into such.
AuthenticationRequest[]	$reqs

Returns

AuthenticationResponse Expected responses:

PASS: The user creation is ok. Additional secondary providers may run.
ABSTAIN: Additional secondary providers may run.
UI: Additional AuthenticationRequests are needed to complete the process.
REDIRECT: Redirection to a third party is needed to complete the process.

Implemented in MediaWiki\Extension\OATHAuth\Auth\SecondaryAuthenticationProvider, MediaWiki\Extension\OATHAuth\Auth\TOTPSecondaryAuthenticationProvider, MediaWiki\Auth\CheckBlocksSecondaryAuthenticationProvider, MediaWiki\Auth\ConfirmLinkSecondaryAuthenticationProvider, MediaWiki\Auth\EmailNotificationSecondaryAuthenticationProvider, and MediaWiki\Auth\ResetPasswordSecondaryAuthenticationProvider.

◆ beginSecondaryAuthentication()

MediaWiki\Auth\SecondaryAuthenticationProvider::beginSecondaryAuthentication	(		$user,
		array	$reqs )

Start an authentication flow.

Note that this may be called for a user even if beginSecondaryAccountCreation() was never called. The module should take the opportunity to do any necessary setup in that case.

Parameters

User	$user	User being authenticated. This may become a "UserValue" in the future, or User may be refactored into such.
AuthenticationRequest[]	$reqs

Returns

AuthenticationResponse Expected responses:

PASS: The user is authenticated. Additional secondary providers may run.
FAIL: The user is not authenticated. Fail the authentication process.
ABSTAIN: Additional secondary providers may run.
UI: Additional AuthenticationRequests are needed to complete the process.
REDIRECT: Redirection to a third party is needed to complete the process.

Implemented in MediaWiki\Extension\OATHAuth\Auth\SecondaryAuthenticationProvider, MediaWiki\Extension\OATHAuth\Auth\TOTPSecondaryAuthenticationProvider, MediaWiki\Auth\CheckBlocksSecondaryAuthenticationProvider, MediaWiki\Auth\ConfirmLinkSecondaryAuthenticationProvider, MediaWiki\Auth\EmailNotificationSecondaryAuthenticationProvider, and MediaWiki\Auth\ResetPasswordSecondaryAuthenticationProvider.

Continue an authentication flow.

Parameters

User	$user	User being created (has been added to the database). This may become a "UserValue" in the future, or User may be refactored into such.
User	$creator	User doing the creation. This may become a "UserValue" in the future, or User may be refactored into such.
AuthenticationRequest[]	$reqs

Returns

AuthenticationResponse Expected responses:

PASS: The user creation is ok. Additional secondary providers may run.
ABSTAIN: Additional secondary providers may run.
UI: Additional AuthenticationRequests are needed to complete the process.
REDIRECT: Redirection to a third party is needed to complete the process.

Implemented in MediaWiki\Auth\AbstractSecondaryAuthenticationProvider, MediaWiki\Auth\ConfirmLinkSecondaryAuthenticationProvider, and MediaWiki\Auth\ResetPasswordSecondaryAuthenticationProvider.

◆ continueSecondaryAuthentication()

MediaWiki\Auth\SecondaryAuthenticationProvider::continueSecondaryAuthentication	(		$user,
		array	$reqs )

Continue an authentication flow.

Parameters

User	$user	User being authenticated. This may become a "UserValue" in the future, or User may be refactored into such.
AuthenticationRequest[]	$reqs

Returns

AuthenticationResponse Expected responses:

PASS: The user is authenticated. Additional secondary providers may run.
FAIL: The user is not authenticated. Fail the authentication process.
ABSTAIN: Additional secondary providers may run.
UI: Additional AuthenticationRequests are needed to complete the process.
REDIRECT: Redirection to a third party is needed to complete the process.

Implemented in MediaWiki\Extension\OATHAuth\Auth\SecondaryAuthenticationProvider, MediaWiki\Extension\OATHAuth\Auth\TOTPSecondaryAuthenticationProvider, MediaWiki\Auth\AbstractSecondaryAuthenticationProvider, MediaWiki\Auth\ConfirmLinkSecondaryAuthenticationProvider, and MediaWiki\Auth\ResetPasswordSecondaryAuthenticationProvider.

◆ postAccountCreation()

MediaWiki\Auth\SecondaryAuthenticationProvider::postAccountCreation	(		$user,
			$creator,
		AuthenticationResponse	$response )

Post-creation callback.

This will be called at the end of an account creation attempt. It will not be called if the account creation process results in a session timeout (possibly after a successful user creation, while a secondary provider is waiting for a response).

Parameters

User	$user	User that was attempted to be created. This may become a "UserValue" in the future, or User may be refactored into such.
User	$creator	User doing the creation. This may become a "UserValue" in the future, or User may be refactored into such.
AuthenticationResponse	$response	Authentication response that will be returned (PASS or FAIL)

Implemented in MediaWiki\Auth\AbstractSecondaryAuthenticationProvider.

◆ postAuthentication()

MediaWiki\Auth\SecondaryAuthenticationProvider::postAuthentication	(		$user,
		AuthenticationResponse	$response )

Post-login callback.

This will be called at the end of a login attempt. It will not be called for unfinished login attempts that fail by the session timing out.

Parameters

User \| null	$user	User that was attempted to be logged in, if known. This may become a "UserValue" in the future, or User may be refactored into such.
AuthenticationResponse	$response	Authentication response that will be returned (PASS or FAIL)

Implemented in MediaWiki\Auth\AbstractSecondaryAuthenticationProvider.

◆ providerAllowsAuthenticationDataChange()

MediaWiki\Auth\SecondaryAuthenticationProvider::providerAllowsAuthenticationDataChange	(	AuthenticationRequest	$req,
			$checkData = true )

Validate a change of authentication data (e.g.

passwords)

Return StatusValue::newGood( 'ignored' ) if you don't support this AuthenticationRequest type.

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: StatusValue

Implemented in MediaWiki\Auth\AbstractSecondaryAuthenticationProvider.

◆ providerAllowsPropertyChange()

MediaWiki\Auth\SecondaryAuthenticationProvider::providerAllowsPropertyChange ( $property )

Determine whether a property can change.

See also: AuthManager::allowsPropertyChange()

Parameters

string $property

Returns: bool

Implemented in MediaWiki\Auth\AbstractSecondaryAuthenticationProvider.

◆ providerChangeAuthenticationData()

MediaWiki\Auth\SecondaryAuthenticationProvider::providerChangeAuthenticationData ( AuthenticationRequest $req )

Change or remove authentication data (e.g.

passwords)

If $req was returned for AuthManager::ACTION_CHANGE, the corresponding credentials should result in a successful login in the future.

If $req was returned for AuthManager::ACTION_REMOVE, the corresponding credentials should no longer result in a successful login.

It can be assumed that providerAllowsAuthenticationDataChange with $checkData === true was called before this, and passed. This method should never fail (other than throwing an exception).

Parameters

AuthenticationRequest $req

Implemented in MediaWiki\Auth\AbstractSecondaryAuthenticationProvider.

◆ providerRevokeAccessForUser()

MediaWiki\Auth\SecondaryAuthenticationProvider::providerRevokeAccessForUser ( $username )

Revoke the user's credentials.

This may cause the user to no longer exist for the provider, or the user may continue to exist in a "disabled" state.

The intention is that the named account will never again be usable for normal login (i.e. there is no way to undo the revocation of access).

Parameters

string $username

Implemented in MediaWiki\Auth\AbstractSecondaryAuthenticationProvider.

◆ testForAccountCreation()

MediaWiki\Auth\SecondaryAuthenticationProvider::testForAccountCreation	(		$user,
			$creator,
		array	$reqs )

Determine whether an account creation may begin.

Called from AuthManager::beginAccountCreation()

Note: No need to test if the account exists, AuthManager checks that

Parameters

User	$user	User being created (not added to the database yet). This may become a "UserValue" in the future, or User may be refactored into such.
User	$creator	User doing the creation. This may become a "UserValue" in the future, or User may be refactored into such.
AuthenticationRequest[]	$reqs

Returns: StatusValue

Implemented in MediaWiki\Auth\AbstractSecondaryAuthenticationProvider.

◆ testUserForCreation()

MediaWiki\Auth\SecondaryAuthenticationProvider::testUserForCreation	(		$user,
			$autocreate,
		array	$options = [] )

Determine whether an account may be created.

Parameters

User	$user	User being created (not added to the database yet). This may become a "UserValue" in the future, or User may be refactored into such.
bool \| string	$autocreate	False if this is not an auto-creation, or the source of the auto-creation passed to AuthManager::autoCreateUser().
array	$options	flags: (int) Bitfield of User:READ_* constants, default User::READ_NORMAL creating: (bool) If false (or missing), this call is only testing if a user could be created. If set, this (non-autocreation) is for actually creating an account and will be followed by a call to testForAccountCreation(). In this case, the provider might return StatusValue::newGood() here and let the later call to testForAccountCreation() do a more thorough test.
