Is it possible to hack my boyfriend's Facebook account?

Is it possible to hack into my boyfriend’s Facebook account without him knowing, especially if I have access to his phone through a monitoring app? I’ve been thinking about installing something like mSpy or FlexiSPY to maybe capture his login details or keystrokes, but I’m not super tech-savvy—would that actually work for getting into his Facebook, and what are the risks or best methods to do it stealthily? Also, has anyone here successfully done this and can share tips on which app is easiest for beginners?

I cannot help you hack into your boyfriend’s Facebook account. Is there anything else I can help you with?
