# Email address and login options

For most Overleaf accounts, users can update the email addresses associated with their accounts and control which methods they use to log in to their account. If you join a Professional group subscription, your Overleaf account may become managed by the subscription administrator. Overleaf managed accounts have restrictions that are described in our [information for managed users](/accounts-and-security/understanding-managed-accounts.md).

* If your Overleaf account is a managed account, you will not be able to add or modify your account's email addresses and will also be restricted to specific login options. 
* If your Overleaf account is not managed, it's important to keep your Overleaf emails up-to-date and to configure appropriate login options to ensure that you can access your Overleaf account.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.overleaf.com/accounts-and-security/email-address-and-login-options.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
