Password must Be 6 and 10 alpha numeric characters?

If a website (or other passWord-protected something or other) tells you that you must have a passWord of 6 to 10 alphanumeric characters, that means that your chosen passWord must be at least 6, but no more than 10, characters, which can be letters or numbers. "Alphanumeric" means letters and numbers, but not punctuation or other characters.

So, "pass" would be too short, "thisismyabsurdlylongpassWord" would be too long, and "@#*&@$!^" would not work because it's not alphanumeric. "P4ssw0rd" would be between 6 and 10 alphanumeric characters, although you should choose something less easy to guess than that.
