By default when you first attempt to sign in to Arch your password will temporarily be set as “mastercpr.” Your username and password will also be emailed to you when your Arch account is set up. Whether you’re a site contact, responsible for just one location, or the Global Admin, responsible for hundreds of AEDs, your username will always be your email address. Once you have logged in for the first time you must change your temporary password (refer here to change the password).
