The setting and saving mechanism of key habits

Sorry, my English is not good, and the wrong machine translation may make everyone misunderstand what I mean. I want to express that when I set the key settings and mouse sensitivity of my personal habits, when I don't play on my personal computer, all these settings will be restored to the default. If I can't save my settings, when I go to the Internet cafe to play, my keys need to be reset, which is very troublesome, because BF1 and BF5 will not encounter this situation
