Hello KM((()
My name is Dayarys.
There is no way to know your password, the only way is to reset it, but you need the Internet in the case of a Microsoft account password.
There is another way but it is not always possible and that is by activating the built-in administrator from the recovery environment.
Follow the below steps:
- Press Shift and Restart from the power icon (together)
- Select Troubleshoot.
- Go to Advanced Options.
- Select Command Prompt.
- Type "net user Administrator /active:yes"
- Hit Enter.

Let us know if you need more help.
Sincerely,
Dayarys
