Windows Hello has proven to be a massive convenience for me, and I’m sure for many of you as well. This advanced biometric security system is designed to turn on, securely verify your identity, and log you in to Windows within seconds. And it’s great… when it works.
Admittedly, it’s worked well for me 99% of the time, but there are occasions when it acts like it doesn’t know who I am. As if it’s meeting me for the first time, leaving me feeling a little bit insulted if I’m honest. Anyways, if your Windows Hello is acting like an old acquaintance pretending to not remember you, there are ways to jolt its memory.
Option 1: Improve Recognition
Step 1: Open Windows Settings
Step 2: Select Accounts, then Sign-In Options
Step 3: Under ‘Manage how you sign in to your device’, select Windows Hello Face.
Step 4: Click Improve Recognition.
Step 5: Follow the instructions to completion.
Option 2: Disable and Re-enable
Follow Steps 1 to 3 above, then:
Step 4: Click Remove, then Set up.
Step 5: Follow the instructions to completion.
Hopefully these options fixed your issue. If you are still having trouble, remember that some limitations may be from the camera hardware on your device. For example, cameras tend to struggle if they are facing a direct light source, such as window during the day, as you would appear as a dark silhouette. So you might need to reposition your device for best results.
