An honest comparison for small teams, with June 2026 list prices. Auth0 is an excellent product — this page is about when its pricing model stops making sense for a team under 500 users, and what the EU-native alternative costs instead
We cap tenants at 500 users on purpose — small teams are the product, not the on-ramp to an enterprise sales call. If you'll outgrow that, Auth0 is genuinely the better choice
Auth0 bills by monthly active users (MAUs), so the bill moves with traffic. Signward bills a flat price per user — your user count times the plan price, nothing else
| Signward | Auth0 | |
|---|---|---|
| Pricing model | Flat per-user — €3 / €4 / €5 per user per month (min. 5 users) | MAU-based — Free (25k MAUs), B2C from $35/mo, B2B from $150/mo, plus ~$0.07/MAU overage |
| Enterprise SSO | Every plan, Starter included | B2B plans only — from $150/mo (3 connections) or $800/mo (5 connections) |
| Custom domain | Every plan | Paid plans only |
| Passkeys (WebAuthn) | Every plan, no per-feature upcharge | Available |
| MFA | TOTP + email + backup codes in every plan | OTP on lower tiers; advanced MFA on higher tiers |
| EU data residency | Always — hosted on Microsoft Azure (EU), identity data never leaves the EU | EU region selectable, but Auth0 is a US-owned company (Okta) subject to the US CLOUD Act |
| GDPR tooling | Consent management, data export, tenant deletion, signed DPA — built in | DPA available; tooling varies by plan |
| Security analytics | AI anomaly detection on every login + plain-language weekly digest | Attack protection on paid tiers |
| Scale ceiling | 500 users per tenant — by design | Millions of users |
| Lock-in | Standard OIDC / OAuth 2.0 — migrate in or out anytime; MIT-licensed SDKs | Standard OIDC / OAuth 2.0 |

Full functionality, no feature limits. Cancel before day 30 and you never pay a cent
Start Free TrialIt depends, and we'd rather tell you straight. If you fit in Auth0's free tier and don't need enterprise SSO, custom branding, or guaranteed support, Auth0 free wins — use it. The math flips the moment you need a paid feature: enterprise SSO on Auth0 starts at $150/month (B2B Essentials, 3 connections), while a 25-person team on Signward Standard pays a flat €100/month with SSO, passkeys, and a custom domain already included
Yes — both products speak standard OIDC / OAuth 2.0, so the application-side change is swapping the authority URL and client credentials, typically under 30 minutes with our SDKs (.NET, Python, JavaScript, PHP). User accounts are re-enrolled by email invitation: there is no automated password import from Auth0 yet, so users set a new password or passkey on first sign-in. You can run both providers in parallel during the cutover
Auth0 lets you select an EU data region, but the company behind it (Okta, Inc.) is US-owned, which keeps it in scope of the US CLOUD Act regardless of where the servers sit. Signward is built and operated in the EU, hosted on Microsoft Azure's EU regions, with a GDPR-native stack: signed DPA, consent management, data export, and full tenant deletion. Your users' identity data never leaves the EU
We cap tenants at 500 users by design, there is no SCIM directory sync, and we don't carry the enterprise compliance program portfolio Auth0 does. That's the trade: we build for small teams only, which is why SSO, passkeys, and custom domains fit in every plan instead of behind an enterprise gate. If you need millions of users or SCIM, Auth0 or another enterprise IdP is the right tool
The industry habit of locking single sign-on — letting users log in with their company Google or Microsoft account, or federating with a customer's identity provider — behind expensive upper tiers. On Auth0, enterprise SSO starts at $150/month and the connection count is capped per tier. Signward includes SSO in every plan, Starter included, because for small teams SSO is table stakes, not an enterprise feature
