How many managers can be signed in simultaneously?
You can have an unlimited number of managers and they can all be signed in at the same time using their own username/password.
A Username/Password should NEVER be shared. Always add each user as a new manager or employee so that you can track who made changes and also so that no errors are caused by two people signing into the same user account making changes at the same time.
In the top menu, hover over SETTINGS and choose Add/Edit Managers and enter the additional managers and click edit to set their sign in permissions (ex. Can they approve time off, edit employees ,etc).
Each additional manager will have their own manager username and password (in addition to their employee username if they are also an employee), and there is no limit to how many managers you can add.
