Explanation
Knowledge factors are things you know. While PINs, passphrases, and one-time passwords are all knowledge-based, traditional passwords remain by far the most widely deployed authentication mechanism across virtually all systems worldwide. One-time passwords (OTPs) are increasingly common but still secondary. Passphrases are a subset/variant of passwords. PINs are typically limited to specific use cases like ATMs or device unlocks.
