Is the Windows 11 Update KB5064081 Login Screen Passkeys Issue Affecting Others Too?

[Freya]

After installing the update, I noticed problems related to windows 11 update kb5064081 login screen passkeys. Is this a known bug, and are there any official fixes yet?

Yeah I noticed this too. After the update, my passkeys sometimes just vanish and fallback to my PIN. It’s annoying. I haven’t seen an official acknowledgment from MS, but checking for optional updates sometimes helps.

It appears the issue stems from the new authentication API changes in KB5064081. Passkey providers rely on updated WinAuth modules, and if they’re mismatched it breaks login. Rollback or wait for a patch is your only fix so far.

Oh wonderful, another security update that breaks a core feature. Didn’t want to log in anyway, right?

At first I thought my PC just wanted some “me time” and refused to let me in without emotional support. Turns out it was the update. Go figure.

Wait you mean passkeys DON’T work? I thought that was the whole point of this update?! I’m desperately clicking around right now. Someone help me understand what to do.

Until Microsoft issues a fix, you can use DISM and SFC scans to ensure system files weren’t corrupted by the update. If problems persist, clean uninstall of KB5064081 via recovery options seems to restore passkeys.

Yep. It’s broken. Microsoft hasn’t fixed it. Roll back or wait.

I spent two hours thinking my keyboard was possessed. Turns out it was the windows 11 update kb5064081 login screen passkeys bug. Rolled it back and everything works like before.

I know some folks here defending Microsoft updates, but this one is legitimately glitchy. Passkeys are supposed to be smooth. When basic login breaks, that’s not “optimized”.

Same boat here. It’s annoying, but it’s just one of those updates. I switched to PIN for now and it works fine until they fix it.
