# Progressive Profiling: Collect Customer Data Without Friction Source: https://startwithidentity.com/articles/progressive-profiling-guide/ Last updated: 2026-10-16 License: content by Start with Identity. Cite the source URL. --- [Progressive profiling](https://startwithidentity.com/glossary/progressive-profiling/) collects customer data in small steps over time, asking only for what the current interaction needs, instead of front-loading a long registration form. It is one of the signature patterns of [customer identity](https://startwithidentity.com/guides/fundamentals/what-is-ciam/), because it resolves the tension at the heart of CIAM: the business wants a rich profile, and the customer wants to get in. ## Why front-loaded forms fail Each field on a signup form is a question the customer has to answer before seeing any value. [Baymard Institute's checkout research](https://baymard.com/lists/cart-abandonment-rate) has repeatedly listed being forced to create an account among the leading reasons shoppers abandon a purchase. A long form also invites junk: people who do not see why you need their date of birth will make one up, and that bad data then feeds personalization and analytics. There is a legal argument too. [GDPR](https://startwithidentity.com/regulations/european-union/gdpr/) [Article 5(1)(c)](https://eur-lex.europa.eu/eli/reg/2016/679/oj) requires personal data to be "adequate, relevant and limited to what is necessary." Collecting fields at signup "in case marketing wants them later" is hard to square with that. ## The pattern 1. **Signup: identifier and credential only.** An email or phone number plus a [passkey](https://startwithidentity.com/glossary/passkey/) or password, or a single [social login](https://startwithidentity.com/articles/social-login-guide/). Nothing else unless a regulation requires it. 2. **First real need: ask in context.** Shipping address at the first checkout. Company name and VAT number at the first invoice. Date of birth when the customer opens an age-gated feature. 3. **Preferences: ask where they matter.** Topic interests on the newsletter page, notification channel when the first notification would fire. 4. **Returning sessions: one question at a time.** A short interstitial after login, triggered by rules, with a skip option and a cap on how often it appears. The rules that make it work: one or two fields per prompt, a one-line reason shown with the question, skip always allowed, never ask for something you already have or can derive, and never ask the same question twice in a short window. ## Where the data comes from - **Social and federated sign-in.** [OpenID Connect](https://startwithidentity.com/standards/openid-connect/) defines standard claims (name, email, locale, and others) that the identity provider can release when you request the `profile` and `email` scopes. Request only what you will use, and check `email_verified` before trusting an address. - **In-context prompts** inside the product, which convert best because the reason is obvious. - **Post-login interstitials** run by the CIAM platform, which suit attributes every app needs. - **Verification flows** for attributes that must be proven, not asserted. See the [customer identity verification guide](https://startwithidentity.com/guides/compliance/customer-identity-verification-guide/). ## Implementing it in CIAM Start with the profile schema. Every attribute should carry metadata: its source (self-asserted, social provider, verified), when it was collected, and the purpose it was collected for. Provenance matters because a self-asserted date of birth and a document-verified one are not interchangeable. Then decide where the prompting logic lives. Platform-side, a post-login hook or journey step checks which attributes are missing and which rules have fired, and inserts a prompt. App-side, the application reads the profile and asks in context, then writes back through the profile API. Most teams need both: the platform for cross-app attributes, the app for contextual ones. Platform support varies. [Strivacity](https://startwithidentity.com/vendors/ciam/strivacity/) lets product teams design registration, login, and progressive-profiling flows in a no-code journey builder, while B2B-focused tools such as [WorkOS](https://startwithidentity.com/vendors/ciam/workos/) state that consumer features like progressive profiling are not their focus. The [top identity orchestration platforms](https://startwithidentity.com/articles/top-7-identity-orchestration-platforms/) article covers the journey-builder category. ## Keep each step compliant Every new prompt is a new collection event. [GDPR Article 13](https://eur-lex.europa.eu/eli/reg/2016/679/oj) requires the purpose and lawful basis to be given at the time data is obtained, and the [CCPA](https://startwithidentity.com/regulations/united-states/ccpa-cpra/) requires notice at or before the point of collection. If the lawful basis for a field is consent, capture it as a separate, recorded consent, as described in the [consent and preference management](https://startwithidentity.com/articles/ciam-consent-preference-management/) guide. If your service is directed to children, the age question belongs at signup, not later, because [COPPA](https://startwithidentity.com/regulations/united-states/coppa/) obligations start before any other data is collected. ## Measure it Track signup completion rate, profile completeness over 30 and 90 days, prompt dismissal rate per field, and downstream use of each attribute. A field with a high dismissal rate needs a better reason or a better moment. A field no system reads should not be collected at all. ## Choosing a platform Compare CIAM options in the [best CIAM platforms](https://startwithidentity.com/rankings/best-ciam-platforms/), [best CIAM for startups](https://startwithidentity.com/rankings/best-ciam-for-startups/), and [best CIAM for high scale](https://startwithidentity.com/rankings/best-ciam-for-high-scale/) rankings. When evaluating, ask to see a post-login prompt triggered by a rule, attribute provenance in the profile, and a profile API your apps can write to, using the [how to evaluate CIAM](https://startwithidentity.com/guides/buyer-guides/how-to-evaluate-ciam/) guide. [Deepak Gupta's CIAM Compass](https://guptadeepak.com/ciam-compass/) maps profile and journey capabilities across platforms. The best profile is not the longest one. It is the one where every field was given willingly, for a reason the customer understood, and is still in use.
