A spy wanted to get into a secret club for some information.

He waits outside and spies on two members.

When Member 1 knocks on the door, the guard knocks back 6 times and the member replies with 3 knocks and he was let in.

When member 2 knocks on the door, the guard knocks 12 times and the member replies with 6 knocks and he was let in.

So the spy thought he had cracked the logic so he knocked on the door.

The guard knocked ten times and the spy replied with 5 knocks but he was not let in.

What was the correct secret password and what’s the logic behind it?

The Correct secret Password is 4 knocks.
The logic behind is:
If the guard knocks 6 (SIX) times, the member should knock 3(Count of letters is 3 in the word 'SIX').
If he knocks 12(TWELVE), then member should knock 6(Count of letters is 6 in the word 'TWELVE').
If the guard knocked 5(FIVE) times, then a spy should have knocked 4 ( Four letters in the word 'FIVE') times.

the correct secret password was three. - ten is three letter ( T, E, and N ) word.

A man worked for a high-security institution, and one day he went in to work only to find that he could not log in to his computer terminal. His password wouldn't work.

Man-"Hey boss, my password is out of date."
Boss-"Yes, that's right. The password is different, but if you listen carefully you should be able to figure out the new one: It has the same amount of letters as your old password, but only four of the letters are the same."
