2. The password has not been changed for a long time. The digitized keyboard will leave fingerprints of frequently-entered characters. The thief can guess based on these numbers.
Can not imagine how to avoid such unsafe settings? So smart lock manufacturers have made a virtual password this feature
What is a smart password?
The virtual password refers to the fact that when you enter the unlock password, in order to prevent being spied by others, you can add arbitrary garbled characters before and after entering the correct unlock password.
