Registering OAuth redirect URIs securely

OAuth, passkeys, biometrics, device registration and recovery.

Identity and sessions1 min readEditorial methods

Redirect URIs determine where authentication results return. Broad matching or uncontrolled destinations weaken the flow.

Evaluation approach

Register exact intended URIs and bind callbacks to requests. Assess the platform's link mechanism.

Application example

Keep test and production registrations distinct. A callback for one environment must not be accepted by the other.

Limits and considerations

A well-formed URI does not prove its relationship to a user session.

Can test routes remain in production?

Audit obsolete and overly broad targets. Adding a redirect should be a reviewed security change rather than routine unchecked configuration.

Checks and decisions

  • Register exact targets
  • Separate environments
  • Reject unexpected returns
