Yes—this sounds more like a Windows 11 sign-in/credential-provider or domain authentication issue than genuinely incorrect passwords. Similar reports in 2026 describe users getting “incorrect username/password” specifically after locking or waking, with restarting temporarily fixing it.

For a business/domain environment, I’d check:

 

Windows build/KB: Compare affected PCs and recently installed cumulative updates. One 2026 report linked the behavior to KB5077181.

Domain authentication: Check DC/security logs at the exact failure time. Also test nltest /sc_verify:<domain> and confirm DNS/time synchronization.

Try “Sign-in options” → Password/PIN instead of the currently selected credential method.

Entra/Windows Hello: If these are Entra-joined or hybrid-joined devices, investigate Windows Hello/credential-provider and cached-token issues.

Install the latest Windows 11 cumulative update on affected machines; Microsoft recommends keeping Windows updated for sign-in problems.

Most useful diagnostic: record the Windows 11 version/build and KB number from one affected PC, plus whether the machines are AD domain joined, Entra joined, or hybrid joined. That should narrow this down considerably.
