Can multiple domains (e.g. app.client.com and admin.client.com) be connected to the same Simple Login project?
Yes: configuration of allowed domains and redirect URLs to manage app + admin (multi-domains) on the same project.
Comparisons & architecture choices (Auth0, build vs buy, lock-in)
Simple Login vs Auth0: what are the differences for a startup or a freelancer?
Simple Login = fast, developer/startup-oriented, ready flows + white-label + teams/roles/subscriptions. Auth0 = very comprehensive/enterprise but often more complex and costly at scale.

The use of Simple Login is designed to minimize the impact on performance. With its lightweight architecture, response times remain fast, even with a large number of users. This ensures a smooth experience for your users.
What are the steps to migrate to Simple Login from an existing solution?
To migrate to Simple Login, start by assessing your current architecture, then follow the steps in the documentation to integrate the SDK. It is important to test the authentication and ensure that all user data is transferred correctly.
Why not code authentication yourself (JWT, sessions)?
Auth is not 'just JWT': sessions, refresh, revocation, emails, security, and maintenance. Simple Login saves you time and reduces risks.
Does Simple Login create a lock-in risk?
There is always a dependency, but you can limit lock-in through standards (OAuth/webhooks) and an abstraction layer on the app side; Simple Login integrates cleanly.
