I think may be easier to people forget and insert the correct pin that unlock the full balance than the correct finger. What is easier for you to remember: Use this finger or this pin? For me is the specific finger.

I was thinking the exact opposite
if there was a gun to my head the odds of me remembering my 6 digit trick pin is low but I’d remember to use my pinky to unlock and not my thumb
Optionality is always better you can always have both
Shouldn’t be too hard to remember which finger.. 🖕🏻😜
