1. Unable to refresh the credentials of this account
(1) Open vs, help ---> send feedback ---> report a problem, and then enter a website.
(2) Click "Sign in" to log in to your Microsoft account (my problem has been solved, so I can't get this screenshot, but my problem is not solved here), and then you can refer to other answers on the Internet or Help, probably a pop-up window will appear. The content of the pop-up window is a URL and a series of voucher codes. Enter the URL and enter the voucher code, then enter vs and log in again, and you should be able to log in.
PS However, after I logged in to my account here, I didn’t get a pop-up window and no URL and voucher code, but a long series of red error messages (my heart: help!!!), and then changed the prompt when I entered vs login again I "Can't add this account". The lucky ones should stop here and log in to the account directly, but unfortunately I can only continue to find a way.
2. Unable to add this account
(1) Open vs, Tools ---> Options.
(2) Account ---> Select "System Web Browser" ---> OK.
(3) Enter vs, log in to your own Microsoft account again, it will no longer open the login interface with your own browser of vs, but will open the login interface with your own default browser, and then enter the account and password normally. climbed up.
PS At this point, I have already registered my own account. But there may still be people who can't log in (I guess), because I saw someone give the following help in the process of finding the previous solution: open your default browser, find its "Internet Options" (with The browser does not have this name, but you can use this as a search keyword to find this thing in different browsers), and then turn on "Automatically detect settings" (as shown in the screenshot below). I boldly guess that if you want to successfully log into your account in vs through this step, you should complete all the steps in "point 2".
I hope this article can bring you help. The road to learning is long. I hope we can all learn something and encourage each other!
