How to use two Claude accounts at the same time on Windows

Personal account on one side, company account on the other. Instead of signing out and in at every switch, keep each Claude account in its own Mezi instance.

Step by step

  1. Download and install Mezi, then choose the folder where instances will live.
  2. In Mezi, click "Add app" and pick Claude from the installed apps list.
  3. Click "New instance" and give it a name, like "Work" or "Personal".
  4. Open the instance and sign in with the other account. The sign-in comes back to the instance you are using.

The free plan opens 1 instance at a time, alongside your normal app. With Pro, you can open as many as you want at once.

Tip

Give instances clear names: the name shows in the taskbar, next to Mezi’s mini sun.

Frequently asked question

Does this increase Claude’s usage limits?

No. Each account keeps its own limits and rules. Mezi only separates the logins on your PC. Check the service’s terms about using multiple accounts.
