When you enter the user name and password incorrectly in the clone on git, the window for entering the user name and password will no longer pop up automatically. The errors are as follows:

fatal: Authentication failed for 'http:xxxx.git/''

After some Baidu found a solution, just input

git config --system --unset credential. helper

Then press enter, enter the URL of GIT clone copy, and then press enter

At this time, the command line will appear asking for the user name, then enter your git user name and press enter

Next, a small window will pop up, prompting you to enter your password, enter your git password, and click OK
