-# How we generate passwords for users created via integrated authentication methods
-GitLab allows users to create accounts using different [authentication methods](../administration/auth/README.md) like OmniAuth, SAML, SCIM, Smartcard authentication etc.
-These authentication methods does not require the user to explicitly create a password for their account upon signup. However, to maintain data consistency, GitLab requires each user account to have a password associated with it.
+# Generated passwords for users created through integrated authentication
+GitLab allows users to set up accounts through integration with external [authentication and authorization providers](../administration/auth/README.md).
+These authentication methods do not require the user to explicitly create a password for their accounts.
+However, to maintain data consistency, GitLab requires passwords for all user accounts.
 For such accounts, we use the [`friendly_token`](https://github.com/heartcombo/devise/blob/f26e05c20079c9acded3c0ee16da0df435a28997/lib/devise.rb#L492) method provided by the Devise gem to generate a random, unique and secure password and sets it as the account password during sign up.
