Then your password text won’t look like a password, but as a meaningless text inside the mess.
It can be on any handwritten paper, such as outdated invoice, old unused reminders or notes, etc.
If you absolutely have to write down a password on a physical medium, sure. A much better alternative would be to use a password manager that lets you sync passwords between devices.
I personally recommend Bitwarden. Their free version is one of the better ones available and they are very transparent about the security measures they take.
That is a great tool, I use it too.
The only safe way to store your passwords is in an encrypted form in password manager. It’s also simply more comfortable because the manager will autofill your credentials in most cases. I would recommend checking out Bitwarden and KeePassXC.
