Done, now Windows 10 devices will automatically lock when you (and your phone) are away. Thus, other people will not be able to access the computer.

Some of the problems I found

As practical as it sounds, I encountered a few issues when using Dynamic Lock using Bluetooth. These problems include:

  • The music stops after a few seconds — I can still connect to the Bluetooth speaker, but the music stops after a few seconds of playing.
  • Windows 10 does not reopen when approached — This feature seems to only lock when far away, but not unlock when close.
  • There are no specific settings regarding distance — We cannot set how many meters of distance it takes until Windows 10 locks itself.

Apart from that, this method is quite practical for maintaining privacy, especially in open spaces such as offices, schools, or other public places.
