# Account and access problems

> Fix sign-in problems and find presentations that appear to be missing.

## I cannot sign in

1. Confirm that you are opening the correct Presenton Cloud or self-hosted address.
2. Enter the username or email for that account again instead of relying on an old saved browser value.
3. Check Caps Lock and remove accidental spaces before or after the password.
4. Try a private browser window to rule out an expired session or browser extension problem.
5. If you still cannot sign in, contact your workspace or Presenton administrator to verify the account and reset access.

<Note>
  A Presenton API key beginning with `sk-presenton-` cannot be used to sign in to the browser. It authenticates REST API and MCP requests only.
</Note>

## My presentations or templates are missing

* Confirm that you signed in with the same account and opened the same Presenton deployment you used before.
* Check whether you are viewing Presenton Cloud, a local installation, or a different self-hosted server. Their workspaces are separate.
* Ask your administrator whether your account was changed, removed, or recreated. Content belongs to the account that created it.
* If only one presentation is missing, check whether it was duplicated, renamed, or deleted from another browser session.

## I was signed out while working

Sign in again, reopen the presentation, and check the latest saved state before repeating any edits. If sign-outs continue across browsers, record the time they happen and ask your administrator to check session or authentication changes.

## If you administer self-hosted Presenton

* Confirm that the user is opening the correct server and that the account still exists under **Admin → Users**.
* Use the documented reset or recovery flow instead of editing authentication data in `/app_data` manually.
* Credential override and authentication recovery can invalidate existing browser sessions and API keys.
* If all users appear new or all content is missing, confirm the container mounts the original persistent directory at `/app_data`.

See [Authentication](/self-hosted/configuration/authentication) for user management, credential rotation, and administrator recovery.
