I&#x27;m not sure about &quot;big&quot;, it all depends on how much you trust 1password and what your threat model is. For me, the advantage of keepass is that I don&#x27;t need to upload my credentials anywhere, or trust some closed source blob running in the browser, etc. It has a XML format that enables things like this client to be created.<p>1password has the advantage of excellent platform integration on iOS, and various browser extensions with auto-fill.
