I have memorized my master password. I have written it down in a couple of books as well. I never take those books out of home. All my other passwords are in plain text files (encrypted with the master password) in my computer. It works fine. I don’t trust third party software to store my passwords, and anything open source doesn’t beat my plain text file tbh.
