Do you feel you are secure? A lot of people aren't obviously by the recent cyber hack at cra.I know of a few people that are just ripe for picking. Very few are seniors btw.
2fa is another good idea but password manager plus mobile devices plus 2fa makes an annoying but still insecure loop. Recently crooks have been cloning sims to get access to 2fa codes. If you have a code changing keychain, that is a great device that really helps lock things down.It's always about convenience.. if systems will require to change passwords often then there is a big chance that people will just change "qwerty" to "qwerty1" and so on.
I switched many years ago to a password manager like LastPass with YubiKey. I have no idea what my passwords are and they are either max allowed or 64+ characters. Each site has a unique and strong password and it gives me comfort at night.
I've recently forced my parents to switch to a password manager as well because of many reasons (e.g. you can configure emergency access if needed). They didn't like the idea but now they are pretty happy with it.
They are very easy to use and you can choose how much security or comfort you want (e.g. I don't have autosuggestions/autofill enabled). Of course, there is this trust issue with the password manager. You basically need to choose one that you trust and preferably the one which wouldn't able to restore access to your vault if you forgot the master password. Also, I would say that you do need at least 2FA enabled for the passwords managers. Pls, don't rely only on a master password as it can be compromised e.g. by a key logger.

FWIW, in the past, the vast majority of password managers stored the database either in the clear or with crap encryption. People need to make sure they do their research to make sure they arent setting up the equivalent of a password.txt file on their desktop.
The password manager I use has a recovery key with ~20 words (similar to cryptokeys). If you choose to use this, keep that piece of paper very secure as it is the keys to the castle.
