I know this sounds crazy but changing a password to something you want to keep in the front of mind kind of worked quite well for me. The main reason is it makes you think about it multiple times a day.
Last year I changed my phone password to "Rocliffe" in numbers. Then with a mask and no face recognition, the number of times I had to spell that word into my phone per day (literally dozens) meant I was constantly reminded of it.
It reminded me that the deadline of a writing competition called the Bafta Rocliffe was fast approaching and I needed to keep writing and editing my piece toward it.
I honestly think it helped remind me it was something I wanted to achieve on the daily.
PS: I've changed it now so you can't hack my phone...
