Firmware lock, what could cause it?

[Ictoo]

In the morning I start up my mac and I get the firmware password, I type it in and getting recovery / forgotten password. I click restart and it boots up as normal. No problems, I can shut down and restart and it will boot to the OS with no problem.

But it happened again this morning, Firmware popped up. I have no real idea why this is happening and it's just lucky I know the firmware password. I posted this in Big Sur as i've only ever had this happen since upgrading(Few weeks ago)

Anyone have an idea of what I can try / what could be causing this? This is a 16" 2019 mac

Try a SMC reset?

Hi! Were you the one who set up this password originally?
If so, have you tried to remove it via Recovery Mode -> Restart -> Go back to Recovery and Set it up again?
Looks like a glitch, tbh)
