Is it okay to use a pin on your phone to unlock bitwarden when the pin is relatively simple?

Hi, i’ve had a security scare recently so i changed my password to something very long. (20-30 letters, written down.) Obviously, i can’t put that in everytime I want to use a password. I used a randomly generated pin (6 numbers), but the combination itself feels too.. simple? I’m not sure how to explain it without straight up giving away the pin. (It’s not something obvious like 123456 or anything.)

My question is if there’s any risk involved outside of my phone being stolen. I’m assuming no since even if someone guesses my pin, I have 2FA on. But i’m really new to this sort of stuff, so.
