Given that,

There are ten digits, and repetition is allowed. For each of the six options, you can apply the Fundamental Counting Principle.

Thus,

\mathrm{ n=10\times 10\times 10\times 10\times 10\times 10}

\mathrm{ n=1000000}

Therefore,

The possible number of password combinations is 1000000 ways.
