This behaviour is by design. The reason is that sometimes the user may have two sets of credential helpers, one for one set of domains, and another for another. For example, I believe AWS has its own custom credential helper. Git calls credential helpers until it finds a credential, and then it sends store commands to all of them. A credential helper which has no credentials for a domain will generally respond with no credentials. If you want to override the credential helpers in the `.git/config` file, you can do so by first writing an empty value, like so: [credential] helper = helper = "store --file=./.git/git-credentials" -- brian m. carlson (he/him or they/them) Toronto, Ontario, CA
