Argon2iPasswordHash is not available¶
The following exception may bubble up since TYPO3 v9 during login:
#1533822084 TYPO3\CMS\Core\Crypto\PasswordHashing\InvalidPasswordHashException
Configured default hash method
TYPO3\CMS\Core\Crypto\PasswordHashing\Argon2iPasswordHash is not
available. If the instance has just been upgraded, please log in to the
standalone install tool at typo3/install.php to fix this.
Explanation¶
If an instance has just been upgraded and if argon2i hash mechanism is not available locally, the default backend will still try to upgrade a given user password to argon2i if the install tool has not been executed once.
Reasons¶
This typically happens only if a system has just been upgraded and a backend login is performed before the install tool has executed silent upgarde wizards.
Solutions¶
Please see Password hashing troubleshooting.
