VetBadger utilizes Google authentication. This means that if you have a computer where the Chrome browser is logged in to a google account, Google auth will skip steps and use this login for you.
If you intend to have multiple users using the computer, you will want to add multiple profiles to Chrome.
Once you have done so, if you change the profile associated with Chrome (the icon in the upper right hand of the browser) this will change who Google will automatically log in to VetBadger.
If you change profiles and you are not switched in VetBadger, you will want to log out of VetBadger and log back in again.
