If I write it down, I will lose it. I do have some passwords that follow a specific pattern that I can remember easily for sites I might need to access outside of having KeePass on a machine (haven't put it on my phone).

I love this idea, I hate having to have a actual database to keep after and secure, and I wish it could be done in a way that wouldn't require that, but sites have too many variables for passwords that for me, literally, this wouldn't work on sites I use every day.
