Afer update app passwords broken

i have update my nextcloud from 12 to 13. I use the updater ( and have to Authentication me with
php -r '$password = trim(shell_exec("openssl rand -base64 48"));if(strlen($password) === 64) {$hash = password_hash($password, PASSWORD_DEFAULT) . "\n"; echo "Insert as \"updater.secret\": ".$hash; echo "The plaintext value is: ".$password."\n";}else{echo "Could not execute OpenSSL.\n";};'

The update works fine but after i have to set my app passwords new. I have not changed my password
What does the app passwords reset after the update?
