Managing password manager across multiple users

Altttt84

So lets say that I have a few users configured on GOS for work, social media etc. and on every one of them I need to login to some accounts. Now all of the secured credentials are stored in an online password manager like bitwarden so the only option to login somewhere is to copy the username and password from there.
Is it then good to have my password manager installed on every user and to some extend decrease security of it or do I have some other and better option?

I'm using a local database for this. I make a backup when I create a new entry by merging it with a database on a USB stick. When I need it in another profile I merge it with the database on that profile. There is always a complete backup of the database if the device fails, I don't have to trust or rely on a service. Privacy and security will never decease this way. You can do this with KeePassDX which I have installed in each profile. I think it has options to sync online but I like to keep my databases offline.

FOSSOS I also think that local backups of databases are crucial and personally have some secured.
However my main concern is security of storing all my passwords in every profile and what happens to them when one of the profiles gets compromised. Because having an option to separate some apps if others get exploited is one of my main reasons for using multiple users.

Altttt84 what you could do is only merge your databases into the backup. That way each profile has separate entries but your offline backup has all of them. You can pick which entries you want to merge with certain profiles by adding entries to a secondary database and using that as a database to merge. As an example if you want all of your social media passwords that are in your owner profile in a new social media profile you can add all of those to a new database in your owner profile and move that file to your social media profile and merge it with the database in this profile. You could use the inter profile sharing app or a USB stick to do this. It will be extra work to do this but that way you can keep passwords separate while having a complete backup on USB and on a profile that you don't expect to ever get compromised and you will never have to trust a service to manage your passwords.
