Run two Zoom accounts on Mac
Signing into a second Zoom account normally signs you out of the first. A MacDupl instance keeps both signed in at the same time, each in its own app.

What you get
- Both accounts stay signed in. Zoom instances get per-instance Keychain isolation, so signing into one no longer signs the other out.
- SSO logins just work. Sign-in links follow whichever instance you're using, so “Login with Google” completes where you started it.
- Separate meeting identities. Each instance carries its own account, profile and settings.
- Its own Dock icon. Colour-tinted per instance, so the right Zoom is one click away.
Install it from the vendor's own download page, not the Mac App Store. App Store builds are sandboxed: their data lives in a shared container that a copy would still read, so they can't be cloned. MacDupl's picker grays those builds out and shows you this same advice.
Verified hands-on. Zoom additionally gets per-instance Keychain isolation, which is what stops one login from evicting the other.
- Gets per-instance Keychain isolation specifically — the fix that stops one Zoom login from signing the other out.
- Sign-in callback links (SSO, “Login with Google”) are routed to whichever Zoom instance is frontmost.
How to set it up
- Pick the app
Open MacDupl and choose Zoom from the list of apps installed on your Mac. - Name and colour it
Call it “Work”, “Personal” or a client's name, and give it one of nine icon tints. - Hit Create
About two seconds later there's a new Zoom in your Dock — sign into the second Zoom account — the other stays signed in, no more sign-out loop.
Questions about Zoom
Why did signing into a second account log me out before?
Zoom stores its credentials in a single shared location. MacDupl gives each instance its own isolated Keychain, so two accounts can hold sessions at once.
Does “Login with Google” work in an instance?
Yes. macOS delivers a sign-in callback link to one app only, so MacDupl points those links at whichever instance is frontmost. MacDupl needs to be running for that; the optional background setting keeps it available even with the window closed.
Can I be in two meetings at once?
Each instance is a separate app with its own account, so both can be running. Whether that's useful depends on your camera and microphone — macOS asks each instance for those permissions separately.
Does the App Store version work?
No — install the direct download from zoom.us, which clones normally.
