Do you memorize your passwords or write them down?  

Some I memorize but since I don't like using the same password for all my accounts, I make use of browser extensions that allow me to save them. I don't think it is a good idea to write them down as you can lose them or someone else can get ahold of them.

Me same hhh I can't remember all of them so I have to write down on notebook, in phone too in case I forgot to bring that notebook.

I only have 5 accounts that are of importance where I need to make sure the passwords is not the same. I can easily remember them but I use the same one with a slight variation for everything else so I don't have to write them down or anything.

I have 6 accounts and my passwords are all different. So I write them in my notebook and carry it everywhere. Even I had stored them in my phone, but 2 years ago, I lost my phone and had to change all my passwords. Such a trouble you see!  

I manage them in my brain! I don't like writing stuff down because I misplace things. I also don't trust saving it to my computer. I think it is best to memorize things like this.
