A PIN number can be used to log into the Time Portal Mobile app without having to enter a user name and password.  This 4-digit number must be unique for each user on a device and is usually specified immediately after the first log in.  Once you are logged in, you can change your PIN number by selecting the Change PIN option on the Home screen.

The Change PIN option will display the Change Login PIN screen described below.

To specify a new PIN number, just tap any four numbers on the Change Login Pin screen as illustrated below. Your new PIN number will be saved as soon as you tap the fourth number. 

Since a confirmation prompt is not presented, please be sure to remember your new PIN number as you enter it.  If you forget your PIN number at the login screen, you can log in with your user name and password then reset the PIN number as described above.
