Sorry for the late reply - did not notice your mail in time. Git has the concept of credential "helpers" which can also cache the (valid) credentials. I think, GfW has the so-called Git Credentials Manager (GCM) [1] as the default credential helper since v2.29. A no-brainer way to make Git use no credential helper is to explicitly turn it off, if any: git -c credential.helper="" command [arguments] See the "gitcredentials" manual page (run `git help credentials). I have no idea how this would translate to what Matlab shell provides. Quite possibly, one can control GCM in some way, but I personally have zero experience with it. Just in case, note that GfW has a dedicated mailing list [2] though I'm not sure you could get more luck there in this particular case.
