# Participant Can't Log In to the Client Panel
If a participant is having trouble logging in to the Client Panel, start by checking their status in the system — it will tell you what to do next.
## Check the participant's status
Go to the *Participants* tab and open the participant's profile. Check their registration status.
### Not invited
The participant hasn't received an invitation to register yet. Click the *Invite to ActiveNow* button directly on their profile — the system will send them an email with a registration link.
### Invited
The invitation has been sent, but the participant hasn't used it yet. You can resend it — click the *Invite to ActiveNow* button on their profile.
### Registered
The participant already has an account in ActiveNow. If they still can't log in, continue with the steps below.
## Check the email address
Ask the participant to make sure they're logging in with the email address that appears in their profile in your system. You can check the address directly in the participant's profile.
## Reset the password
If the participant is using the correct email address but still can't log in — they're entering the wrong password. They can reset it [at this link](https://app.activenow.io/users/password/new). After entering their email address, they'll receive a message with a link to set a new password.
{% hint style="warning" %}
When setting a new password, the participant should type it manually — not use the browser's autofill. The browser may suggest the old password from before the reset, which would prevent the new password from being saved correctly.
{% endhint %}
{% hint style="info" %}
If the participant is trying to log in through the mobile app, it's worth checking whether the app is updated to the latest version. It's also worth making sure the phone's operating system is up to date — outdated software can cause login issues.
{% endhint %}

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.
Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:
```
GET https://help.activenow.io/en/client-management/participant-cannot-log-in.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
