When trying to perform git commands like git push in vscode, an error like “fatal: Authentication failed for” may occur. This article introduces the cause and solution for this error.

The main cause of this error is that, due to recent git/github updates, a token is now required instead of a password when pushing to github.
As a countermeasure for this error, you can use the following git store command to record the github credential token to a file.
$ git config credential.helper store
After executing the $ git config credential.helper store command, I was able to push to the repository without having to enter PAT every time I push. Cache only works temporarily.
