# Breaking: #66669 - Backend LoginController refactored {#breaking-66669}

See [forge#66669](https://forge.typo3.org/issues/66669)

## Description {#description}

The backend login has been completely refactored and a new API has been introduced.
The openid form has been extracted and is now using the new API as well.

## Impact {#impact}

All former member variables of the  `LoginController` class have been removed or made protected, together with
some, now pointless, hooks and their related classes.

The deleted hooks are:

-   `$GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['typo3/index.php']['loginScriptHook']`
-   `$GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['typo3/index.php']['loginFormHook']`

The removed class and its alias:

-   `TYPO3CMSRsaauthHookLoginFormHook`
-   `tx_rsaauth_loginformhook`

## Affected Installations {#affected-installations}

Any code manipulating the BE login.

## Migration {#migration}

Use the new backend login form API.
