Does AcuSensor require a password?

The AcuSensor token is automatically created for each Target. You do not need to specify the token yourself.

Should you want to use a custom token, you can specify this from the Target Configuration -> AcuSensor panel -> Change button, and choose to Set AcuSensor Token.
