OAuth2 & Single Sign-on
A Login That Combines Security and Convenience
The login is the front door of your application — and often its biggest security hole. We build sign-in procedures to current industry standards: OAuth2 and OpenID Connect for securely connecting external identities, single sign-on for seamless access, two-factor authentication for sensitive areas.
For your users, that means signing in with the account they already have — Google, Microsoft, Apple or the company's own Active Directory. No additional password to forget or reuse. For your company, it means central control. When an employee leaves, their access to every connected application ends in one stroke.
We have implemented these procedures in many projects — from employee portals with Microsoft login and customer apps with Sign in with Apple to API access with JWT tokens. We also secure our MCP servers for AI assistants with full OAuth2, including a consent screen and fine-grained permissions. For us, security is architecture, not an afterthought.
What modern authentication means for your project
Seamless access
Users sign in with the account they already own. Fewer passwords, fewer support requests, higher adoption — from day one.
Central control
Access is managed in one place. Onboarding and offboarding happen centrally — departed employees lose all access immediately.
Standards instead of homegrown solutions
OAuth2, OpenID Connect and JWT are vetted industry standards. We rely on established libraries instead of risky in-house builds — auditable and future-proof.
