Frequently asked questions about Simple Login
20 questions
Launch a strong authentication for your startup (MVP → production)
How to quickly integrate Simple Login into a web or mobile app?
Quick integration via SDK + hosted login page: you configure your project, enable email/OAuth, then manage sessions and users without recoding the entire flow.
Does Simple Login manage sessions, refresh tokens, and secure logout?
Yes: sessions + refresh tokens + revocation for secure logout, with webhooks to synchronize your services.
Is Simple Login suitable for a multi-tenant (B2B) app with teams, roles, and permissions?
Yes: native multi-tenancy with teams, roles, and permissions for B2B apps.
Indie hackers & solo builders (auth without hassle)
I am an indie hacker: is Simple Login worth it instead of coding my own auth?
Yes: you save time and avoid security pitfalls (sessions, tokens, email flows) with a ready-to-use hosted auth.
What is the difference between magic links and email verification in Simple Login?
Email verification = confirm the email inbox. Magic link = log in without a password via a link. Both are complementary.
Can I start with an MVP and then add OAuth, teams, and subscriptions?
Yes: you can start 'light' and then enable OAuth, multi-tenant, roles, and subscriptions.
Agencies & freelancers (white-label, multi-projects, multi-domains)
Does Simple Login allow for white-label authentication with my branding?
Yes: white-label auth UI (branding) with ready-to-use login/register flows.
How to manage multiple clients/projects with Simple Login without mixing everything up?
You separate by projects/environments and isolate domains, redirects, OAuth, and webhooks; multi-tenancy is useful if your product is multi-client.
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.
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.
Security, compliance & operations (OWASP, webhooks, payments)
What security features does Simple Login cover to avoid common mistakes?
Ready flows, email verification, magic links, sessions + refresh tokens, webhooks: Simple Login covers the areas where 'homemade' auth breaks most often.
Does Simple Login provide webhooks to synchronize my backend (user created, login, etc.)?
Yes: user event webhooks to synchronize your backend (provisioning, roles, onboarding, etc.).
Does Simple Login also handle payments and subscriptions (SaaS) or is it separate?
Yes: Simple Login can manage payments and subscriptions in addition to auth, useful for a SaaS (consistent user/tenant/plan).
