Fortunately, I don't have a problem remembering passwords. I have a very good long term memory. I was told by a neurologist that, because my memory is on the left side of my brain, normal for right handed people, my memory got very strong, as it worked harder than normal, because of my seizures stemming from the right side of my brain.

Now, my short term memory is another thing. Being in my early 60's it's getting bad.

I use the same password on all the sites I go to. There may be some that I need to use a different password. For those, I use stickies on my computer.

I pretty much use the same one for everything. And write them in a notebook.
I always forgot. I had to restart all over. To many questions just for a new password… OMG🤔

Passwords are a pain on all sites... I have a diary which I write them down in which I keep in a special place... If I don't write some down, my memory certainly won't remember them all!
