Correct user identification is one of the most technically important aspects of product analytics — done wrong, you have disconnected anonymous and authenticated user journeys, inflated user counts, and unreliable funnel analysis. We implement user identification correctly: anonymous ID generation and persistence, identify calls at authentication events, alias resolution for merging pre- and post-signup events, and cross-device identity strategy.

Frequently Asked Questions

Anonymous events and authenticated events appear as separate users. Signup funnels are broken (the same user appears twice). Active user counts are inflated. Retention analysis is unreliable.
An alias call merges two distinct user IDs — typically the anonymous ID the user had before signup and the identified user ID they have after. This connects pre-signup behaviour to the user's profile.
When a user logs in on a new device, their authenticated ID links the new device session to their existing profile. Pre-login sessions on the new device remain anonymous and aren't merged.
Via server-side API calls or by synchronising user data from your backend to analytics tools at key events (signup, plan change). We implement the most appropriate method for your stack.
Yes — we implement user identification to respect consent preferences. Users who haven't consented to analytics are tracked anonymously or not at all, depending on your consent configuration.
