This guide concerns the Typo3 module "t3ext-infomaniak-auth" which allows users to log in to your Typo3 site (whether it is hosted by Infomaniak or not) using their Infomaniak credentials.

Preamble

• Allowing login via an Infomaniak account on your Typo3 site enables your visitors to comment, register for courses, or access any member-exclusive content with a single click, without having to create a new account.
• This saves them time and is a safer method for you, as you do not have to manage additional passwords.
• The operation of this external module is identical to the options Sign in with Google", "Sign in with Facebook" or "Sign in with Apple"; it uses the standard protocols OAuth2 and OpenID Connect to enable single sign-on (SSO).
