How much can one extra space cost?

There was a curious and very painful situation at the same time.
We have many registered customers and many of them are those who have never logged in.

It is useless to write to clients on such issues - few of the offended clients will answer why he was offended.
Therefore, we were not lazy and began stupidly to call everyone and ask, why, they say, did not come in?
The answer was almost the same for everyone:

-We could not enter the login password.
