Microsoft has acknowledged a new issue affecting Windows 11 versions 24H2 and 25H2, which arose from the August 2025 non-security preview updates. Users have reported that the password button is missing from the lock screen sign-in page, although the area where the icon should be remains functional for entering passwords. This issue was first noted on November 30, 2025, and there is currently no workaround other than clicking the invisible area to sign in. Microsoft is working on a resolution and will provide updates.
