I did that recently as a backup measure, 1Password comes with a good "emergency kit" that you can print out and store in a safe place. It has instructions on how to access the vault and the password in plain text.
The big advantage of a password manager that is consumer friendly (Like 1Password) is that you can store everything in there (documents, passport, notes) and it will be accessible to whoever needs access to it. Not some obscure command line knowledge necessary.
It is also a lot easier than having hundreds of papers / letters in your house. Even if it's not about the security aspect, having everything in one place is a big advantage.
I also use 1PW and agree it is a good choice. I would be cautious with saving too much information and files (documents, keyfiles etc) in it. With their latest update to v8 they removed the ability to print as PDF or save an attachment, so you will have a very hard time getting it out. Only way seems to be screenshot (too bad if the text is longer than a screen) or sharing via mail (you get the draft and from there copy the attachment). Am not sure if they try to hold your data hostage (VC "capture value" play) or greatly overshot on security.
i asked their support and they acknowledged the removal of PDF-printing, regarding attachment: i didnt mean an attached file but the ability to e.g. save a secure note as an attachment. my fault for using bad english. your remark that you can save an attachment via download button is correct.
