# Authentication When signing up, you select either GitHub, [Google](/settings/integrations/authentication/google-single-sign-on.md), or [Microsoft](/settings/integrations/authentication/microsoft-entra-id-single-sign-on.md) as the initial authentication method for your Swarmia organization. Once the signup is complete, it's possible to switch the authentication method to any of the three or configure [Okta](/settings/integrations/authentication/okta-single-sign-on.md). If you use GitHub to authenticate, all members of the connected GitHub organization can access Swarmia. If you have connected multiple GitHub organizations, you can control whether users need to be members in all or any of the organizations to access Swarmia. All users will be able to view metadata (e.g., pull request names) from integrated repositories. Use caution with sensitive repositories. When installing the app, it's possible to manually choose GitHub repositories you want to connect to Swarmia. --- # Agent Instructions: 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.
