Random::otp returns string instead of int

[binaryfire]

Hey @valorin,

Is there a reason why Random::otp() returns a string? Wouldn't it be better to return an int since it's numeric?

It needs to be a string so it keeps the leading zeros. An integer won't keep them, which is the whole point of the function.

Otherwise, you'll end up with less than 6 digits or be forced to start at something like 100000 instead of 000000.

Good question though - I should make it more obvious.
