You can set up a Two-Factor Authentication (2FA) requirement for staff on your account.
As prerequisites to enable 2FA for a staff member, you must have the Manage Accounts permission enabled with your permission set, and the staff member for whom you are setting up 2FA must have a cell phone number under their account set up.
To set up 2FA for a staff member, go to Account > Staff Members and select the Staff tab. Click Set Up next to the staff member to set up 2FA.
Next, enter your password (not the password of the staff member) and click Confirm.
You will see a success message at the top of the screen.
Under the 2-Fac Sec column, you will see Active.
When the user logs in, they will be prompted to enter a security code. The staff member can click Request Token via SMS and the code will be sent to the cell phone listed in the staff profile. Or they can set up the Authy app described in our article How do I set up 2-factor authentication in my account?
