IMO, these rules need to be enforced by the password system itself.
So, exactly what constitutes a "special" character should be built
into it, and if an invalid character is detected, then a useful
error message should be generated.

Anyway, I wasn't trying to write out a fully comprehensive set of rules.
I was simply stating what I consider to be the minimum security.
Guidelines, not rules.

Another good guide is:

Enforce changing of passwords on at least a monthly basis.
Do not permit re-use of old passwords.

See my other message about writing down.

You have found the bank of Larn.
I can explain it for you, but I can't understand it for you.
I speak only for myself, and I am unanimous in that!
