Password spraying involves attempting to sign in to many accounts while guessing passwords from a list of the most likely options. This attack relies on the assumption that at least some accounts will be using insecure passwords.

Compare this to brute-forcing, which involves guessing many passwords against a single account, in a way that is usually more apparent in logs.
