The password length must fall within the range accepted by the NIST 800-63B document. Allowing passwords that are too short increases the risk of an attacker successfully brute forcing passwords. Shorter passwords create significant compliance violations. Ensure that a password policy is being enforced for each password credential store in use on your instance. Ensure that the password policy mandates a minimum password length of at least 15 characters and maximum password length of at least 64 characters. For each password credential store record in the Password Reset Credential Stores \[pwd\_cred\_store\] table: 1. Ensure that a password policy is being enforced for each password credential store in use on your instance: For each password credential store record in the Password Reset Credential Stores \[pwd\_cred\_store\] table, ensure that **Enable password policy** field is activated. 2. Ensure that the password policy mandates a minimum password length of at least 15 characters and maximum password length of at least 64 characters. Navigate to the Password Policy \[password\_policy\] record referenced in the record's **Password policy** field. Ensure that the **Minimum Password Length** field is set to at least 15 and **Maximum Password Length** field is set to at least 64. 3. Further instructions on configuring a password policy can be in the documentation: [Enable password policies on your instance](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/brazil/markdown/platform-security/authentication/enable-password-policies.md) Further instructions on configuring a password policy, see [Enable password policies on your instance](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/brazil/markdown/platform-security/authentication/enable-password-policies.md). ## More information
Attribute Description
Configuration name - Password Reset Credential Store \[pwd\_cred\_store\] table - Password Policy \[password\_policy\]
Configuration type - Table records - Table records
Data type - Boolean - Integer
Recommended value - The **Enable password policy** field on each Password Reset Credential Stores \[pwd\_cred\_store\] record must be activated\(true\). - The **Minimum Password Length** on the associated Password Policy \[password\_policy\] record must be at least 15. - The **Maximum Password Length** on the associated Password Policy \[password\_policy\] record must be equal or less than 64.
Default value - The **Minimum Password Length** on Password Policy \[password\_policy\] records is 8 by default. - The **Maximum Password Length** on Password Policy \[password\_policy\] records is 100 by default.
Fallback value - The fallback value of **Minimum Password Length** on Password Policy \[password\_policy\] records is 8. - The fallback value of **Maximum Password Length** on Password Policy \[password\_policy\] record is 100.

Security risk - Severity score: 5.9 - CVSS score: Medium - Security risk details: Allowing passwords that are too short increases the risk of an attacker successfully brute forcing passwords. Shorter passwords create significant compliance violations.
Functional impact Instances don't suffer any impact from a minimum password length of 15 or maximum password length of at least 64.
