I use one vault for accounts and separate vault for standard notes(using offline mode) and separate vault for file encryption like cryptomator.
Is that good strategy to separate or just put it all in one vault?
Why compartmentalize?
There is no right or wrong way. Whatever works for you. All passwords and authentication credentials are E2EE (provided you’re using one of the recommended password managers). So, save info in it in the way it works for you.
Your strategy is essentially Security by Compartmentalization, and from a technical standpoint, it’s a solid architecture.
Stick with it. Just make sure your backup strategy is as segmented and disciplined as your storage.
Separating vaults is a good strategy but it’s likely requiring extra effort keeping them on up-to-date (especially if you are using multiple devices) and you have to have good backup strategy as well
