Authentik, an open source identity provider, ready to manage sign on and identity on first boot.
Authentik is an identity provider that supports SSO, multi factor authentication and protocols such as OAuth2, SAML and LDAP. Organisations use it to centralise authentication and manage access across many applications.
cloudimg ships Authentik hardened and fully patched on Ubuntu 24.04, preconfigured so the provider is reachable on first boot. You create the administrator account during first run, and the image is supported 24/7.
