Hello fabbras,
Thank you for posting in Microsoft Community forum.
There are a few possible troubleshooting steps you can try:
- Check your keyboard input and layout at the sign‐in screen.
• Sometimes the default keyboard layout (or an on‐screen keyboard if you’re using that) might not match what you expect—for example, the placement of symbols or numbers could be different.
• If available, try clicking the “Show password” icon or using the on‐screen keyboard (if you haven’t already) to make sure your characters are interpreted correctly.
- Confirm that your Surface is connected to the Internet.
• When you change your Microsoft account password on another device, your Surface needs to connect online to update its cached credentials. If it’s not connected (or has a weak/unstable connection), it might still be using old cached info.
• Try connecting it to a known Wi‑Fi network or even a wired connection (if possible) by restarting your router or the device.
- Allow time for Microsoft account synchronization.
- Use different sign‑in options if available.
• Since facial recognition wasn’t working and PIN wasn’t set up properly, you’re stuck with the password option. If your account offers any additional recovery or sign‑in options (like a security key or one‑time code via your mobile), see if that might help.
- Boot into Safe Mode or the Recovery Environment.
• If nothing seems to work and you have important data on the device, you might boot into Safe Mode.
• To access Safe Mode, hold down the Shift key and select Restart from the sign‑in screen’s power icon. Then navigate through Troubleshoot → Advanced options → Startup Settings and restart into Safe Mode. Once in Safe Mode, check if you can sign in with your new password.
- Consider temporary local account workarounds.
• If you can access Microsoft account recovery options or if you’re able to enter the Recovery Environment, you may be able to create a new local administrator account to back up data and perform further troubleshooting.
- If your device is in one domain environment, you can ask your domain admin to reset password or reset PIN to see if it helps.
I hope the information above is helpful.
If you have any question or concern, please feel free to let us know.
