TYPO3 Core

Installing v9 via composer without rsaauth causes the felogin not to work.
No error message is issued anywhere.

The reason is that the FactoryDefault sets FE|loginSecurityLevel to "rsa" even though rsaauth is not installed.
For the BE we have proper detection and a proper reset to level "normal".

root composer.json holds:

"roave/security-advisories": "dev-master",
"typo3-ter/static-info-tables-de": "^6",
"typo3/cms-core": "^8",
"helhum/typo3-console": "^5",
"reelworx/sitesetup": "dev-upgrade_8",

(sitesetup from a private repo)

composer.json from sitesetup:

"typo3/cms-core": "^8.7",
"typo3/cms-scheduler": "^8.7",
"typo3/cms-fluid-styled-content": "^8.7",
"typo3/cms-recycler": "^8.7",
"typo3/cms-rte-ckeditor": "^8.7",
"typo3/cms-felogin": "^8.7",
and other non-core exts

After composer install we run typo3cms install:setup to do the rest.

ext:rsaauth is not enabled therefore.
