Windows 11 forces PIN validation on boot for Edge, Teams and Phone Link

The repeated prompts don’t establish that a scheduled task is overriding your settings. Turning off the Windows Hello sign-in requirement also doesn’t prevent apps from requesting account verification. And resetting Ngc again could introduce more authentication disruption rather than fix the underlying issue.

Since several apps are affected but OneDrive isn’t, Windows’ shared account authentication is worth investigating. OneDrive working doesn’t rule that out because it can maintain a separate session.

Two useful next steps won’t require changing your startup or sync preferences:

• Open Settings > Accounts > Your info and Email & accounts. If Windows itself shows Verify or Fix now for the Hotmail account, complete that there rather than separately in each app. Note whether the warning returns after a restart.
• Capture what happens during one failing startup. Record the exact prompt text and time, then check Event Viewer > Applications and Services Logs > Microsoft > Windows > AAD > Operational, if available. Despite its name, that log can contain useful Windows authentication-broker errors; not every event there will be relevant.

If Windows shows no account warning, or verification only lasts a couple of restarts, take those errors to Microsoft support and request investigation of Web Account Manager/account-token persistence across restarts. That’s a more specific lead than another PIN reset.

There isn’t a supported universal switch that forces all three apps to accept silent sign-in when their account session requires verification. Avoid disabling identity services or deleting more authentication caches until there’s evidence identifying the failing component.
