Why a truly random password is strong?
The entropy will increase according to the number of potential characters (that are random) that are added. Entropy is not increased with each letter that is chosen “rule-driven” (so for same length passwords, entropy is lower). Therefore, in principle, this new password with non-alphanumeric characters is more secure than the prior one with alphanumeric characters alone.
