I don't see password managers as a secured way because once your device is lost, you have lost access to your password managers also.
No! You can have backups in case something bad happens (e.g., you lose your phone/computer, disaster, mental ailness, brain damage)
I use Bitwarden and I periodically do backup maybe thrice a month. What I usually do is exporting the unencrypted .csv file and store it on a multiple flash drives in separate secure location while the master password and its associated backup email is written on a laminated paper to keep it from wear and tear. With that, you'll have no reason that you lose access to your PM.
I also that you can backup your Keepass database both on online and on physical storeage though.
Making multiple copies of your passwords on paper make your password more vulnerable.
Maybe I am missing something, but I surely don't understand why making multple copies isnt good LOL.
Because it increases the risk that someone finds it IMO.
Moreover, your way of doing is only efficient for very tech-savvy people but most of users will never do that, or one or two months at most, and will give up. It's way too burdensome for the average Joe, for just an account on a crypto forum. Don't forget this iron law of opsec :
Security at the expense of usability comes at the expense of security.For decades, the advice from information security experts was to change your passwords frequently and use numbers, capitals, and special characters. But we humans are bad at creating randomness, and we’re bad at remembering things. So inevitably people used simple words, names, birthdates, and sayings, swapping out letters with similar-looking special characters. Hackers can crack these kinds of passwords in a matter of seconds.
In an effort to make secure systems, the prevailing password advice actually made the systems less secure. Or, as the user AviD now-famously put it on Stack Exchange, responding to the XKCD comic: “Security at the expense of usability comes at the expense of security.” In other words, if your “secure system” isn’t easy to use, people won’t use it, negating the security benefit.

When you use passphrases, also keep the following in mind:
Four words should be sufficient. Five words is better.
Don’t choose from the most common words, and don’t choose quotes or sayings. The words should be as random as possible.
Use a unique passphrase for every account you own. That way, if one passphrase is ever exposed, the other accounts remain secure.
