Hi,
Thank you for sharing your question. I understand how frustrating it is when you suddenly can’t sign in to Hotmail directly from your home PC, especially when everything works normally from your workplace. It’s completely reasonable to feel confused, because being asked for extra authentication each time can feel like your password is being rejected even though nothing has changed on your end. This usually happens when Microsoft’s account security system detects a sign‑in attempt from a location, device, or network that it doesn’t fully recognize, and it triggers additional verification to confirm that you are the legitimate account owner. When this happens consistently on one network but not another, it often means that the home IP address, browser cookies, or device trust settings changed recently, which makes Microsoft treat the sign‑in as a new or less‑trusted environment. It may also follow certain security‑related Windows or browser updates, but Microsoft has not confirmed any widespread login issue; instead, the behavior matches normal security‑prompt patterns.
The most effective way to resolve this is to sign in from your home PC and choose the option to mark the device as trusted, ensure cookies are not being cleared automatically, and verify that your browser or security software isn’t blocking Microsoft login cookies or sign‑in sessions. You can also try signing in with a different browser to see if the trusted‑device session is saved correctly.
To better understand what might be triggering the security check, may I ask whether your home browser was recently reset, your network provider changed your IP address, or you started using a VPN? Please follow up and I’ll help you get your account signing in normally again.
I hope this helps.
Best Regards,
Noel
