Apple ID password

Where can I find my Apple ID since I use Face ID for everything I forgot it but don’t want to reset it.

if the only option is to reset it, I’m just going to save the new password somewhere anyway so I don’t forget it again, since Apple promotes Face ID which in turn causes me to never need my Apple ID password, until I need it for some reason on my Apple TV to confirm an app because the device confirmation doesn’t work , because my phone remote usually doesn’t connect to my Apple TV and tells me to make sure they are on the same network which they are……then I have to reset my Apple ID anyway because i cannot remember it…..but ya. I love how secure my device is.
