title: Managing Two-Factor Authentication
description: Reset a user's 2FA, configure per-user SSO enforcement, and recover from lockouts.

This guide is for administrators. For general 2FA usage, see [Two-Factor Authentication](/features/two-factor-authentication).
## Reset a user's 2FA
A user who has lost their authenticator app and all backup codes cannot sign in on their own. Any administrator can reset the affected account from the Settings UI.
1. Open **Settings → Users**
2. Find the user in the list. Users with 2FA enabled show a shield icon in the action column
3. Click the shield icon and confirm the reset
After the reset:
- The user can sign in with their password only, no second factor is required
- Their existing sessions are invalidated, so any stale browser tabs have to sign in again
- The action is recorded in the audit log with the administrator's username
Instruct the user to enrol again from **Settings → Account & Security** as soon as they are back in. The account is unprotected until they do.
## Emergency recovery from the command line
If every administrator has lost access to 2FA and no one can sign in through the UI, reset the admin account directly from the host running Sencho.
From a shell on that host:
```bash
docker compose exec sencho node dist/cli/resetMfa.js
```
Replace `` with the admin's account name. On success the command prints a confirmation line and exits 0. Sign in with the password, then re-enrol immediately.
The command respects the container's `DATA_DIR`, so it always acts on the same SQLite database the application uses. It writes an audit log entry attributed to `cli` so the action is auditable after the fact.
Turning on **Developer Mode** in **Settings → Developer** surfaces additional authentication diagnostics in the backend logs. These are helpful when investigating a 2FA support ticket, and can be turned off again once the issue is resolved.
## Per-user SSO enforcement
When SSO (LDAP or OIDC) is configured, users with 2FA enabled sign in through SSO without a second factor by default. SSO is already an authenticated flow, and requiring a TOTP on top is extra friction that most teams do not need.
Each user can opt into stricter behaviour by flipping **Require 2FA even when signing in via SSO** on their own Account & Security screen. There is no admin-wide override, every user decides for themselves.
If your organisation needs to force 2FA for every SSO sign-in for every user, raise this with the Sencho team, it is not exposed as a global policy today.
## What a reset changes in the database
For completeness, a reset does the following to the target user:
- Clears the stored TOTP secret and all remaining backup codes
- Rotates the user's session version, which invalidates any outstanding session cookies
- Leaves the account otherwise unchanged, the username, password hash, role, and audit history are preserved
Nothing about the user's SSO bindings changes. If the user was signing in with SSO plus 2FA, they simply resume SSO-only sign-in after the reset.
