Also, KeepassXC and OG KeePass with a plugin can auto-open another vault from an entry in the primary vault. This works well if you have the more secure vault open a less secure vault, or in my case open a shared vault used for common passwords off a network share at work.

I also preach the tiered password security model. For the common, frequently used passwords that don't need max security, I just use the browser store (with a copy in KP).
