And if you already have an IdP, connect it directly.

A true European open source service provider.
We deploy, support, and contribute to the best open source productivity tools. You get a fully managed workspace without the complexity of self-hosting or the trade-offs of big tech.
Our platform builds on La Suite Numérique. Open source tools trusted by 200,000+ French government users, built together with the French, German and Dutch governments.
Mosa is named after the river flowing through Maastricht, the city where the European Union was born. Just as that treaty united nations in collaboration, we're continuing that spirit through open source software.
