Password complexity criteria are criteria that determine how strong or secure a password must be for a user account. Password complexity criteria can include requirements such as minimum length, uppercase letters, lowercase letters, numbers, special characters, etc. Three of the valid password complexity criteria while setting up password policies are:

Complex: At least 8 characters, 1 uppercase, and 1 number

Very Complex: At least 8 characters, 1 uppercase, 1 number, and 2 special characters

Very Complex: At least 8 characters, 1 uppercase, 1 number, and 1 special character Simple: At least 8 characters and 1 number is not a valid password complexity criterion while setting up password policies, as this criterion does not meet the minimum security standards for Oracle Cloud applications. Very Complex: At least 6 characters, 1 uppercase, 1 number, and 1 special character is also not a valid password complexity criterion while setting up password policies, as this criterion does not meet the minimum length requirement of 8 characters for Oracle Cloud applications.
