Login is where the customer relationship starts
Registration and login shape the first customer experience. If they are slow or inconsistent, people drop off, and fragmented data makes it harder to understand who your customers are and what they have agreed to.
What are the benefits with a CIAM solution?
Passkeys, multifactor authentication, and passwordless login raise the bar for anyone trying to take over an account. Customers get through with less friction.
Customers log in once and move between your applications without starting over. Fewer passwords, fewer support tickets, and fewer abandoned sessions.
Verify each customer through MitID, BankID, Vipps, Freja, or the Finnish Trust Network, then keep future logins fast and cost-effective.
Bot traffic, credential stuffing, and account takeover attempts target login first. Detection and step-up authentication stop them before they reach your customers.
Collect, store, and act on customer consent in one place. Marketing, product, and legal teams then work from the same source.
Customer data gathered across applications rather than scattered across systems. Easier to analyze, easier to correct, and easier to delete when a customer asks.
Households, shared accounts, memberships, and business customers rarely fit a one user, one account model. CIAM supports delegated access without custom workarounds.
Campaigns, launches, and seasonal peaks put pressure on login. A CIAM platform handles millions of users and still responds quickly.
Identity proofing and eID
Identity proofing verifies a customer's identity once, against a trusted provider. In the Nordics that means MitID in Denmark, BankID or Vipps in Norway, BankID or Freja in Sweden, and the Finnish Trust Network in Finland. From then on, the customer is authenticated directly in the CIAM solution.
Login is the part of your service every customer uses, and comes back to on every visit.

Support for privacy and regulatory work
Bringing customer identity data together in one place makes privacy work easier to manage and easier to document. Here are four areas worth planning for from the start:
GDPR: One place to see what you store, act on consent, and handle deletion requests on time.
European Accessibility Act: Applies to registration and login flows in consumer-facing digital services.
eIDAS 2.0: Adds the EU Digital Identity Wallet as a new way for customers to prove who they are.
AI agents: When an agent acts for a customer, you need to know who is logging in and with what authority.
FREQUENTLY ASKED QUESTIONS
CIAM is how organizations manage the identities of their customers. It covers registration, login, authentication, consent, customer profile data, and access to digital services. Where traditional IAM handles employees and internal systems, CIAM handles customers, members, and other external users at much larger scale.
Both manage identity and access, but the conditions differ. IAM typically covers a known population of employees, with access decided by role and approved internally. CIAM covers customers who create their own accounts, expect a quick login, and can arrive in the hundreds of thousands. Experience, scale, and consent handling weigh much heavier in CIAM.
Many organizations start with login built into each application. It works until you add the second and third service, at which point customers end up with several accounts, and your teams maintain the same logic in several places. A CIAM platform gives you one login across services and one place to manage security, consent, and customer data.
ommon Nordic options are MitID, BankID, Vipps, Freja, and the Finnish Trust Network. Social login through Google or Apple is also widely used, and eIDAS 2.0 will add the EU Digital Identity Wallet.
CIAM gathers customer identity data in one place, which makes it easier to document what you store, record and act on consent, and handle access and deletion requests. Compliance still depends on your processes and how the solution is configured, but the work becomes far more manageable.
No. CIAM matters wherever external users log in. That includes member organizations, media and subscription services, energy and utilities, public services, banks and insurers, and B2B portals where business customers manage their own users.
We help Nordic organizations choose, design, implement, and run customer identity solutions. That includes advisory work early on, platform selection, integration with the surrounding systems, access models for complex customer relationships, and ongoing support once the solution is live.
