# Clean up dormant Auth0 accounts and cut your monthly bill

> Find accounts that have not signed in for months, block or remove them in bulk with the right safeguards, and post a record of every sweep to Slack.

## What it does

- Lists every account that has not signed in within a window you choose, either 90, 180, or 365 days, with the email, sign up date, total logins, and exactly how long the account has been idle
- Shows your current monthly active user count next to a login and signup trend, so you can see what a cleanup session is actually saving you
- Lets you select accounts and act on them in bulk, either blocking them quietly so they stop counting against you, or removing them permanently behind a typed confirmation
- Protects accounts that still hold a role by keeping them out of the removal path entirely, so an admin or billing owner never gets deleted by accident
- Posts a summary of everything you blocked and removed to a Slack channel when you finish, giving your team a written record of the sweep

## What you'll need

- An Auth0 login with permission to view and manage users in your tenant
- A Slack workspace where the summary of each cleanup session can be posted
- An idea of how long an account should sit idle before you consider it dormant, usually somewhere between three months and a year

## Prompt

Build me a cleanup console for trimming dormant Auth0 accounts before they inflate our monthly active user bill. This is an interactive triage and bulk action surface that I open when I want to run a cleanup sweep, not a scheduled report. The whole point is that I actually retire accounts from inside the app.

The main screen is a triage table of dormant accounts. At the top I pick an inactivity threshold of 90, 180, or 365 days. Use Auth0 Search Users to fetch accounts whose last login falls before that cutoff, with a Lucene range query against last_login and search_engine set to v3, in the shape last_login:{* TO 2026-05-16} where the date is computed from the threshold I picked. Each row shows email, connection, signup date, total logins, and days since last login. Sort by days since last login descending by default, so the most stale accounts are on top. Accounts that have never logged in at all will not match a last_login range query because the field is absent, so handle those deliberately rather than silently dropping them, either by querying for them separately or by clearly scoping the table to accounts that have logged in at least once.

Beside the table put a header tile with the current tenant monthly active user count from Get Active Users Count, and next to it a login and signup trend from Get Daily Stats over the trailing 30 days. This is the cost context for the sweep, so it should be visible while I work rather than buried on another page.

Let me filter the table by connection so federated enterprise accounts can be reviewed separately from database signups. There is no operation for listing tenant connections, so build the filter options from the connection values present in the loaded result set rather than trying to fetch a connection list.

Page based user search is capped at the first 1,000 results, so on a large tenant the table cannot simply page to the end. Handle this honestly: page through results with page and per_page up to that ceiling, tell me plainly when the result set is truncated, and push me toward narrowing the sweep with a longer threshold or a connection filter instead of pretending I am seeing everything.

I select rows and take bulk action from the table. Every selection must default to block rather than delete. Blocking uses Update User to set the blocked attribute, which retires the account quietly and is reversible. Deleting uses Delete User and is irreversible, so it sits behind a typed confirmation box where I have to type a confirmation phrase before it will run.

Before any delete is allowed, check each selected account with List User Roles. Any account that currently holds a role is excluded from the delete path entirely. Show a clear badge on those rows explaining why they cannot be deleted. They can still be blocked, but the delete action must be unavailable for them, not merely discouraged. Run this check as part of preparing the delete, so a role assigned after the table loaded is still caught.

Auth0 user ids embed the identity provider, in the shape auth0|66f1 or google-oauth2|1057, and must be URL encoded when used in path segments for the update, delete, and role lookup calls. Get this right or the write actions will fail on anything other than plain database users.

Track what happens during a session. Keep a running record of which accounts were blocked and which were deleted, with the email, connection, and days idle for each, and show it as a session panel so I can see what I have done so far. When I finish, a button posts a summary of that session to a Slack channel I choose using the Slack Bot Send a Message operation, listing what was blocked and what was deleted with counts, so the rest of the team has a record of the sweep. Persist the session record so the console still shows the history of past sweeps when I come back to it.

Bulk actions run over many accounts, so process them at a sensible pace and surface per row success and failure rather than failing the whole batch on one error. If an action fails, keep the row in the table with the error visible so I can retry it.

## How to customize

- Change the inactivity windows offered in the picker if your team treats dormancy differently, for example 30 or 60 days for a fast moving product
- Pick which Slack channel receives the end of session summary, and adjust how much detail it includes
- Adjust which sign in methods you review together, so staff accounts from your company directory can be handled separately from ordinary signups

## FAQ

### Will this delete accounts without asking me?

No. Nothing happens until you select accounts and choose an action, and every selection defaults to blocking rather than removing. Permanent removal asks you to type a confirmation first, because it cannot be undone.

### What is the difference between blocking and deleting an account?

Blocking leaves the account in place but stops the person signing in, so it is easy to reverse if someone comes back. Deleting removes the account and its history permanently. Blocking is the safer default for most cleanup sessions.

### Could I accidentally remove an admin or a billing owner?

No. Before you act, the console checks whether each selected account holds a role, and any account that does is kept out of the removal path completely. You can still block it if you want to, but it cannot be deleted from this screen.

### Does this actually reduce what I pay for Auth0?

Auth0 pricing is tied to how many people are active in a given month, so retiring accounts that no longer sign in keeps that number honest. The header shows your current active user count so you can watch the effect of a sweep.

### What if I have tens of thousands of users?

Very large result sets are handled by narrowing the window or filtering by sign in method rather than loading everything at once, so you work through the genuinely dormant accounts in manageable batches.

### Can I review company directory accounts separately from ordinary signups?

Yes. You can filter the table by sign in method, so accounts coming from a company directory or a social login can be reviewed on their own rather than mixed in with regular email and password signups.
