There are 10 digits to choose from (0-9) for each of the 6 digits in the passcode, with repetition allowed, so the total number of possible passcodes is:
10 x 10 x 10 x 10 x 10 x 10 = 1,000,000
Therefore, there are 1,000,000 possible six-digit passcodes.
A passcode on a smartphone consists of 6 digits, and repetition of digits is allowed.
