#$newFile = $this->fileRepository->findByUid($newFileObject->getProperty('uid'));
$newFile = $newFileObject->getUid();

$newFileReference = $this->objectManager->get('Ven\Key\Domain\Model\FileReference');
$newFileReference->setFile($newFile);
$user->addLogo($newFileReference);

.... could solve it myself. just add setter to model and add texts:
/**
* Set alternative
*
* #param \xx\yy\Domain\Model\File $file
*/
public function setAlternative($alternative) {
$this->alternative = $alternative;
}
and to controller:
$newFileReference->setAlternative('your alternative text for image');
