You can switch between multiple WorkGuru tenants without having to enter credentials using the managed linked accounts function.  From the Linked accounts window you can click between accounts you have permission to access. Note: This function requires an existing user account in linked tenant to work.

From your accounts menu, select Managed Linked Accounts

Click +Link new account
The window will prompt for the tenant name and your credentials. These are the same details you would use to log into the tenant directly. Click Save when entered.

If the account details are correct, the account will be added to your linked accounts list.  You can repeat this process to add additional accounts as required.   Click the trash icon to delete any linked accounts you no longer require access to.

You can then switch between WorkGuru tenants without having to enter credentials from the my account menu by clicking on the required tenant listed under the linked accounts.
