New installation with an existing database but not the same salt as the previous setup

Hi,

I had to do a new installation of Matomo but I could’nt retrieve the original salt from the config.ini.php file (long story short, the file is hosted on a AWS ECS Fargate and I can’t connect directly to the container to retrieve the file)

The installation went well, and all seems to be working except the token_auth.

I think this is due to a different salt. Can someone can confirm this ? Is this a real problem if we use a new generated salt ?

Is the salt used for other modules ?

Thank you
