# Logging in with institutional SSO
An authentication option for Overleaf Commons subscriptions.
This page describes one of Overleaf’s login options, institutional single sign-on (SSO), which is offered by some Overleaf Commons subscribers and is implemented using the SAML2 standard.
For more information about login options, please see [Email address and login options](/accounts-and-security/email-address-and-login-options.md#overleaf-login-options). Information about SSO for Professional groups can be found [here](https://docs.overleaf.com/groups/overleaf-group-single-sign-on/setting-up-group-sso).
{% hint style="info" %}
Overleaf Commons single sign-on is a “site wide” SSO implementation that differs from Overleaf Group SSO. If you are a group administrator or responsible for configuring SSO for a group, please see our [Overleaf Group SSO](https://docs.overleaf.com/groups/overleaf-group-single-sign-on/setting-up-group-sso) guides for more information.

## 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://docs.overleaf.com/accounts-and-security/email-address-and-login-options/logging-in-with-institutional-sso.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.
