so you are suggested to write it down and keep 2 paper record at least.
even if you lost /damage one finally. you still have one back up.

Well when you write down a password on a paper you have a greater risk of getting your password stolen so I would not recommend writing down passwords anywhere.

I won't suggest anyone to write down his password.Just remember that password and then use it but don't write anywhere it can be dangereous.
