# Delete registrations

## Introduction

During normal operation, some number of inactive registrations accumulate. An inactive registration might exist because

- A user created a registration, but then deleted the app
- A user created a registration, but didn’t use it
- A user acquired a new device and created a new registration

For these and other cases, use the nnl-mgmt.sh command-line utility to identify all inactive registrations and disable them, then physically delete them from the database. Nok Nok recommends cleaning out inactive registrations once a quarter.

Specify the tenant and protocol family when you use the nnl-mgmt.sh authenticators command. See detailed documentation for the [nnl-mgmt.sh authenticators command](/dpoa/docs/s3suite94-authenticator-commands).

> Before you use nnl-mgmt.sh, you must have assigned the password encryption key to the NNL_PKEY system environment variable. You should have done this in [Step 4. Encrypt Credentials Used by the Server](/dpoa/docs/s3suite94-step-4-encrypt-credentials-used-by-the-server)
