Do you have password nostalgia?

I have found a password that has last been changed in 2008. It is the password of a fairly important account, so I should change it, because it is not the best password.

At the same time, I feel bad about changing this password that has been with me for so long. Especially since I didn't pick this password. My mother who passed away chose this password when she set up my account. It sort of feels like it's the last thing I have from her.

I am conflicted about mitigating a security risk and holding on to a piece of digital nostalgia.

Has anyone else experienced this?
