My aspire a715-71g bios password forgot

Hi
When I using Acer fingerprint PBA (pre boot authentication) software, the app ask me to use this feature you must set Supervisor password in app.
I set supervisor password using same app. 
After rebooting system, before loading windows in bios, the system ask me to enter password. 
I tried to use password that be set in acer fingerprint PBA  but it doesn't work and say wrong password. 
I tried 3 times but system say wrong and give me a unlock password key. 
Please help me.
