Issue: How to fix login error “The username or password is incorrect”?

Every time I start my PC, whether after sleep or restart, I get an error message “Other User. The username or password is incorrect”. My correct username is already in the login box, but I have to re-enter it to continue. This is really annoying and I'd like to fix it. Any tips?

Solved Answer

“The username or password is incorrect” is a bug that emerged with the release of Windows 10 V1709, also known as the Fall Creators Update. This problem is also known as the “sign-in twice” error^[1] as it occurs on the log-in screen after waking the system from sleep or rebooting it.

Although the user enters the correct credentials, he/she receives the “The username or password is incorrect” and has to re-enter the username and password once again. This problem occurs on Windows 10 V1709 version exceptionally and most frequently strikes PCs that were upgraded to the latest Windows 10 build from earlier versions.^[2]

While the error is not critical and is not dangerous, it can be particularly frustrating to users, as they have to enter their details anew each time they want to login to Windows. Therefore, it is not surprising that many users are seeking the “The username or password is incorrect” error fix.

People get the notification about allegedly incorrect info before the Welcome screen. It may show up even if the user hasn’t even tried to enter a username or password. Entering the user credentials for the second time or dismissing the “The username or password is incorrect” error and entering the password and username anew usually provide access to the desktop.

Sign-in Screen Appears Twice in Fall Creators Update with “The username or password is incorrect” notification is not the worst Windows 10 bug. Nevertheless, it’s too irritating to be ignored. Many people reported that alongside the login screen showing up twice, Windows 10 automatically logs in users after every system’s restart. In other words, if you are the User1 and reboot your PC as a User1, you may find your User2 as a signed-in user unexpectedly.

Microsoft has been informed about this bug and has already acknowledged it, so we expect that upcoming Cumulative Updates^[3] will patch the “The username or password is incorrect” error completely. Before that happens, you may fix the problem manually.

According to Windows enthusiasts, the “The username or password is incorrect” at the login screen occurs due to the enabled “Use my sign in info to automatically finish setting up my device after an update or restart” option. If it’s disabled on your PC, then you should try to disable Fast Startup^[4] or check the system for malware.

1. Press Windows key + I and navigate to the Update & Security.
2. Open Windows Update section and click Advanced options.
