Methods that fit your product
Offer passwords, passkeys or email links, and configure the security requirements for your sign-in app. Not every method meets every assurance level.

Does my application have to move to Atom9?
No. Your application can stay where it runs today. It redirects users to Atom9 for authentication and validates the returned identity through OpenID Connect.
Does EU hosting make my whole app GDPR compliant?
No. Hosting is one part of the picture. Your organisation still decides its purposes, lawful basis, notices and retention. Atom9 provides authentication and, on Managed, user-data tools to support that work. Read the responsibilities and controls.
Which providers handle the data?
The deployment’s sub-processor list explains providers and processing locations. Adding an optional external sign-in provider introduces that provider’s own arrangements; EU-hosted authentication does not relocate your existing application’s data.
What can I start with for free?
Login Free gives you a hosted sign-in app with Atom9’s maintained appearance. Choose Pro for white-label editing or Managed for additional user-data tools. Compare the plans and current prices.
