Is it possible for composer to have multiple auth files?

Question

Composer

When authenticating, composer offers to save the data to the user's home directory. This is convenient when it is enough for a resource to simply get a username and password. However, this scheme does not work when you need to use different accounts in different projects for the same resource.
1. Is it possible to specify the auth.json file when requesting composer install/update?
2. Is it possible to have globally different configs or different auth.json?

Answer 1

Found the answer: there is no support for different configurations except for the configuration in the project folder, but this is not recommended.
