# Passcode Expiry

## Overview

In the interest of increased security, you can configure an expiry period for mailbox passcodes from 1 to 365 days. To disable the passcode expiry feature, ensure that it is set to the default value of "0".

Enforcement of the passcode expiry is performed through the TUI interface. Users who log in to the TUI of an expired mailbox are prompted to enter a new passcode.

UM users who do not use the TUI are unaffected by passcode expiry behavior. UM email messages continue to be synchronized and delivered after passcode expiry. Web View users can continue to log in.

## Conditions and Limitations

- This feature is not supported for MiCollab deployments of NuPoint Unified Messaging and must be left at the default setting of "0" expiry.

- By default, the TUI plays back the new passcode to the user. To change this operation to a prompt to "Re-enter new passcode", TUI users must have FCOS feature bit 300 - Enable Secure Tutorial assigned.

- New passcodes are valid only if:

  - they meet existing NP-UM passcode restrictions

  - they differ from the most recent passcode

  - they are successfully confirmed by the TUI (when feature bit 300 - Enable Secure Tutorial is assigned)
