Frequently asked questions

What is OneID®?

OneID® is a unique service that enables people to be in control of their identity online, helping them to secure and simplify their digital life. It works by allowing them to use their existing bank-verified identity with online sites and services that they trust – removing all the fiddly form filling, delays and identity checks currently experienced when signing up to a service or shopping online.

How does OneID® work?

Many of the sites and services consumers use online already use a range of identity-checking services. OneID® uses an customer’s existing bank-validated identity to simply and swiftly sign-up to new services or shop online. Businesses pay a small fee to the bank for providing this validated identity data. This helps banks and businesses, while keeping the customer in control at all times.

How secure is OneID®?

OneID® is a unique privacy-focused free-to-use solution that doesn’t store, see or sell customer data. We use bank-grade security protocols to transfer data between the bank and the service the individual approves. Customers have full control over the data that they wish to share.

Why should individuals use OneID®?

Why not? OneID® provides a quick, safe and easy way to transfer specific data between a bank and a registered 3rd party – with the individuals’ consent. It allows them to take control of their data whilst also speeding up online journeys.

What is a bank-verified ID service?

A bank-verified ID service enables customers to use personal information already held by their bank to prove who they are in order to access online services outside of the banking domain. The bank acts as an ‘identity provider’; it verifies the identity of the person from its own databases and, in accordance with its own policies and FCA requirements, then confirms the customer’s identity to another party. Banks have a very strong interest in ensuring that only authenticated users can access their accounts online, so the identity verification is of a higher standard than can be achieved by any other means.


The bank-verified ID model has been successfully implemented in the Nordic region, with adoption and usage rates exceeding 90%. In Sweden the service is used on average twice a day by every adult and processes 6bn transactions pa. It is used to access almost all commercial and Government services.  

Does OneID® sell data to advertisers or third parties?

We believe privacy is an essential human right and individuals’ use of OneID® is known only to them. We only capture evidence of the consents given, not any personal details. The consent console shows individuals where and when they have provided consent for Digital Identity Net to access their bank account and share their personal data with a relying party.

OneID® will never share data with advertising or analytics companies.
