FrontendUserAuthentication 

\nn\t3::FrontendUserAuthentication()->login($username = '', $password = '', $startFeUserSession = true); 

Login of an FE user using the user name and password

// Check credentials and start feUser session
\nn\t3::FrontendUserAuthentication()->login( '99grad', 'password' );

// Check only, do not establish a feUser session
\nn\t3::FrontendUserAuthentication()->login( '99grad', 'password', false );

\nn\t3::FrontendUserAuthentication()->loginBySessionId($sessionId = ''); 

Login of an FE user using a session ID.

The session ID corresponds to the TYPO3 cookie fe_typo_user. As a rule, there is one entry for one entry in the fe_sessions table for each FE user session. Up to Typo3 v10, the the ses_id column corresponded exactly to the cookie value.

As of Typo3 v10, the value is also hashed.

\nn\t3::FrontendUserAuthentication()->loginBySessionId( $sessionId );

\nn\t3::FrontendUserAuthentication()->loginField($value = NULL, $fieldName = 'uid'); 

Login of an FE user using any field. No password required.

\nn\t3::FrontendUserAuthentication()->loginUid($uid = NULL); 

Login of an FE user using an fe_user.uid

\nn\t3::FrontendUserAuthentication()->prepareSession($usernameOrUid = NULL, $unhashedSessionId = NULL); 

Create a new frontend user session in the fe_sessions table. Either the fe_users.uid or the fe_users.username can be transferred.

The user is not automatically logged in. Instead, only a valid session is created and prepared in the database, which Typo3 can later use for authentication.

Returns the session ID.

The session ID corresponds exactly to the value in the fe_typo_user cookie- but not necessarily the value that is stored in fe_sessions.ses_id. The value in the database is hashed from TYPO3 v11 hashed.

$sessionId = \nn\t3::FrontendUserAuthentication()->prepareSession( 1 );
$sessionId = \nn\t3::FrontendUserAuthentication()->prepareSession( 'david' );

$hashInDatabase = \nn\t3::Encrypt()->hashSessionId( $sessionId );

If the session is to be re-established with an existing SessionId, a (non-hashed) second parameter can be used as an optional, second parameter, a (non-hashed) SessionId can be passed:

\nn\t3::FrontendUserAuthentication()->prepareSession( 1, 'meincookiewert' );
\nn\t3::FrontendUserAuthentication()->prepareSession( 1, $_COOKIE['fe_typo_user'] );

\nn\t3::FrontendUserAuthentication()->setPassword($feUserUid = NULL, $password = NULL); 

Change the password of an FE user.

\nn\t3::FrontendUserAuthentication()->setPassword( 12, '123Password#$' );
\nn\t3::FrontendUserAuthentication()->setPassword( $frontendUserModel, '123Password#$' );
