# Unsupported password characters

# Unsupported password characters {#ariaid-title1}

Release version: Brazil  
Updated September 10, 2026  
![](https://www.servicenow.com/docs/portal-asset/ico-clock) 1 minute to read  
There are password characters that are not supported. Users cannot use these characters, based on ServiceNow password complexity requirements.

To enable a secure network environment, users must use strong passwords that include a combination of letters, numbers, and symbols. These combinations help to prevent unauthorized users who usually use manual or
automated methods to guess weak passwords.

* The password policy requirements are based on the Basic Multilingual Plane (BMP) that contains characters for many languages. ServiceNow instance is shipped with BMPs of around 10000 characters.
* Password characters within these permissible BMPs can be set for your instance. Password characters that do not adhere to these BMPs aren't allowed.

Note:  
User or company-specific characters that cannot be used in the password can be configured in the exclude password list.

For more information about the password policy properties, see [password policy properties](https://www.servicenow.com/docs/SWXCWoHgTRnTJLckDRN~jw "The password policy properties enable you to administrate password policies, exclude list passwords, and apply a password policy during login.").
