Authentication is the process of verifying that a user is who they claim to be. In practical terms, authentication answers “Who are you?” and establishes an identity that the system can trust. Authentication is distinct from authorization, which determines what an authenticated user is allowed to do.
Common Authentication Methods
Applications use passwords, magic links, SSO, and OAuth-based flows. For products that embed editors or expose APIs, OAuth integration often becomes important because it enables secure delegation and integration with identity providers. For embedded editors, consider how authentication affects session continuity. If tokens expire mid-edit, users can lose work. Design token refresh and re-auth flows so the editor can continue saving drafts without forcing a full reload.
Authentication and Privacy Expectations
If you integrate with third-party identity providers, be explicit about what profile data you store. Prefer minimal scopes and avoid syncing fields you do not need. This reduces risk and simplifies compliance work when customers ask for data exports or deletion.
Authentication touches sensitive user data, so it must be designed with privacy in mind. Strong authentication reduces the risk of account takeover, but it also requires responsible handling of identity information. Aligning authentication flows with data privacy principles helps you minimize exposure, log responsibly, and avoid collecting unnecessary data.
Compliance and Security Hygiene
For regulated markets, authentication practices should support GDPR compliance and similar requirements. Use secure transport, protect tokens, limit session duration, and implement monitoring for suspicious activity. From an engineering standpoint, log authentication events with care. Store only what you need, protect logs, and make sure they do not expose secrets. Good hygiene also includes rate limiting login attempts and notifying users of suspicious sign-in behavior.
