Detailed Description

This class is responsible for

‪find the right user, sending out a reset email.
‪create a token for creating the link (not exposed outside of this class)
‪validate a hashed token
‪send out an email to initiate the password reset
‪update a password for a backend user if all parameters match

this is a concrete implementation for User/Password login and not part of public TYPO3 Core API.

Member Function Documentation

◆ findValidUserForToken()

array null TYPO3\CMS\Backend\Authentication\PasswordReset::findValidUserForToken	(	string	$token,
		string	$identity,
		int	$expirationTimestamp
	)

protected

Fetch the user record from the database if the token is valid, and has matched all criteria

Parameters

string	$token
string	$identity
int	$expirationTimestamp

Returns: ‪array|null the BE User database record

◆ generateResetLinkForUser()

UriInterface TYPO3\CMS\Backend\Authentication\PasswordReset::generateResetLinkForUser	(	Context	$context,
		int	$userId,
		string	$emailAddress
	)

protected

Creates a token, stores it in the database, and then creates an absolute URL for resetting the password. This is all in one method so it is not exposed from the outside.

This function requires: a) the user is allowed to do a password reset (no check is done anymore) b) a valid email address.

Parameters

Context	$context
int	$userId	‪the backend user uid
string	$emailAddress	‪is part of the hash to ensure that the email address does not get reset.

Returns: ‪UriInterface

◆ hasExceededMaximumAttemptsForReset()

bool TYPO3\CMS\Backend\Authentication\PasswordReset::hasExceededMaximumAttemptsForReset	(	Context	$context,
		string	$email
	)

protected

Checks if an email reset link has been requested more than 3 times in the last 30mins. If a password was successfully reset more than three times in 30 minutes, it would still fail.

Parameters

Context	$context
string	$email

Returns: ‪bool

◆ initiateReset()

TYPO3\CMS\Backend\Authentication\PasswordReset::initiateReset	(	ServerRequestInterface	$request,
		Context	$context,
		string	$emailAddress
	)

Determine the right user and send out an email. If multiple users are found with the same email address an alternative email is sent.

If no user is found, this is logged to the system (but not to sys_log).

The method intentionally does not return anything to avoid any information disclosure or exposure.

Parameters

ServerRequestInterface	$request
Context	$context
string	$emailAddress
