# Security recovery and credential revocation
|
|
|
|
A password reset is an account-recovery event, not just a password-hash
|
|
change. The operator reset CLI revokes every access path for the target
|
|
account so a stolen session, native refresh token, long-lived API token,
|
|
trusted device, or temporary step-up proof cannot survive the new password.
|
|
|
|
Use the operator procedure in [Password reset](password-reset.md) and prefer
|
|
its hidden stdin prompt:
|
|
|
|
```sh
|
|
docker compose exec app node scripts/reset-password.mjs <username-or-email>
|
|
```
|
|
|
|
Do not put the new password in shell history, a ticket, chat, or logs.
|
|
|
|
## What a successful operator reset revokes
|
|
|
|
The CLI performs one serialized database transaction for exactly one matched
|
|
user. It:
|
|
|
|
1. locks the target account and writes the new password hash;
|
|
2. deletes every web session;
|
|
3. revokes every API access token;
|
|
4. revokes every native refresh token;
|
|
5. deletes every trusted device; and
|
|
6. deletes every live step-up elevation.
|
|
|
|
The safe completion message reports only the username and affected row counts.
|
|
It never prints the password, password hash, tokens, cookies, or health data.
|
|
Unrelated users are not changed.
|
|
|
|
The in-app administrative reset follows the same target-user revocation
|
|
policy for sessions, API tokens, native refresh tokens, and trusted device
|
|
records. Operators should still use the CLI recovery path when rollback-safe
|
|
direct recovery is required.
|
|
|
|
## Rollback guarantee
|
|
|
|
The operator CLI wraps identity resolution, password rotation, and every
|
|
revocation above in `BEGIN`/`COMMIT`. Any error issues `ROLLBACK` before the
|
|
database connection closes. A failed reset therefore does not leave a new
|
|
password paired with old credentials, or old password state paired with only
|
|
some credentials revoked.
|
|
|
|
Treat any non-zero exit as “nothing committed.” Correct the operational
|
|
problem and run the whole command again; do not manually complete a subset of
|
|
the SQL statements.
|
|
|
|
## After recovery
|
|
|
|
- Have the user sign in with the new password and enroll replacement trusted
|
|
devices intentionally.
|
|
- Expect every browser and native client to require a fresh login.
|
|
- Reissue only the minimum API or MCP scopes each integration needs.
|
|
- Review security activity without copying credential material into the
|
|
incident record.
|
|
- If compromise is suspected beyond one account, rotate the affected
|
|
instance-level secrets using the relevant operator runbooks before
|
|
restoring integrations.
