# Soft PIN authentication
# Soft PIN authentication {#ariaid-title1}
Release version: Brazil
Updated September 10, 2026
 2 minutes to read
Soft PIN is a six-digit numeric PIN that verifies a caller's identity during an AI voice agent session.
## When to use Soft PIN {#softpin-authentication__section_kpg_lmj_kjc}
Soft PIN is appropriate for low-risk caller verification, such as confirming a returning user before granting access to self-service tasks.
Soft PIN can be configured as a single factor, the first factor in a multi-factor authentication flow, or a second factor.
Soft PIN is a medium-assurance factor and is not suitable as the only authentication factor for sensitive operations. For those flows, combine Soft PIN with a higher-assurance factor such as Push notification - Okta Verify or a
time-based one-time password (TOTP). For guidance on combining factors, see [Authentication factors for AI voice agents](https://www.servicenow.com/docs/kVN5msZ5XeNd8b6MW5_Xpw "Authentication factors verify caller identity before granting access to AI voice agents. Combining multiple factors helps confirm that only authorized users interact with AI voice agents.").
## How Soft PIN works {#softpin-authentication__softpin-authentication-how-it-works}
Each user enrolls a Soft PIN before it can be used for authentication. Users can change their PIN by re-enrolling at any time.
When Soft PIN is selected as an authentication factor for an AI voice agent service, the agent prompts the caller for the PIN during the session. The platform validates the response against the user's enrolled PIN and returns the
result to the orchestrator.
Note:
* Soft PIN supports both text and voice input.
* Soft PIN factor isn't supported for step-up authentication.
## Enrollment rules {#softpin-authentication__softpin-authentication-enrollment-rules}
The system enforces the following rules on the chosen PIN.{#softpin-authentication__softpin-authentication-enrollment-rules__entry__2}
| Rule | Behavior |
|-|-|
| Length | Exactly six digits. |
| Repetition | No single digit can repeat more than twice consecutively. For example, 111234 is rejected. |
| Sequences | Ascending or descending numeric sequences longer than two digits aren't allowed. For example, 123456 and 987654 are rejected. |
| History | The new PIN can't match any of the user's previous five PINs. |
[Table 1. Enrollment rules]
## Limitations {#softpin-authentication__softpin-authentication-limitations}
A six-digit numeric PIN provides lower assurance than time-based codes or push notifications. PINs are vulnerable to reuse, observation, and social engineering.
## Availability {#softpin-authentication__softpin-authentication-availability}
The administrator manages the following conditions on the instance. Soft PIN enrollment is available when both are met:
* Install Now Assist for Platform `sn_genai_platform` for activating AI voice agents.
* The system property `glide.auth_factors.Soft PIN.enrollment.enabled` is set to true (default).
When the plugin is not installed, no Soft PIN module exists on the instance and the enrollment URL is not available. When the plugin is installed but the property is set to false, the enrollment option is hidden from the user profile,
the navigation menu, and the Service Portal. Users who navigate directly to the enrollment URL see the following message:
`Soft PIN enrollment is not available at this time. Please contact your administrator for more details. `
{#softpin-authentication__softpin-authentication-availability__entry__3}
| Property | Description | Default state |
|-|-|-|
| `glide.auth_factors.Soft PIN.enrollment.enabled` | Controls whether the Soft PIN enrollment option appears in the user profile, the navigation menu, and the Service Portal. Requires the AI Voice Agents plugin. | true |
