Quick Start
In a composer-based TYPO3 installation you can install
the extension EXT:authtoken via composer:
composer require kuhschnappel/authtoken
In TYPO3 installations above version 11.5 the extension will be automatically
installed. You do not have to activate it manually.
Update the database scheme
Open your TYPO3 backend with system maintainer
permissions.
In the module menu to the left navigate to Admin Tools > Maintanance,
then click on Analyze database and create all.
Clear all caches
In the same module Admin Tools > Maintanance you can also
conveniently clear all caches by clicking the button Flush cache.
