Does OneID access my banking information or my account?

OneID does not access that information but rather applies what is known as zero-knowledge proof. What that means is that rather than sending, for example, a scan of your passport to OneID or providing sensitive information, you effectively give OneID permission to ask your bank the simple question “Is this person who they say they are?” What OneID gets back is a binary yes or no, simply verifying your identity without exposing any further information.

If someone hacks OneID, will they have access to my bank account?

The short, simple answer is no. Using OneID does not give them access to your online banking, your account or any other sensitive information the bank has about you. Part of what makes OneID such a good choice for ID verification is that instead of them storing all of that data, it’s all managed by the banks who have to comply with some of the most rigorous data security and KYC regulations in the world.

How long does it take to sign up for OneID?

Because OneID uses bank-verified data and enables you to verify your identity using your online banking credentials, you’re effectively already onboarded if you have access to online banking.

OneID

Use information verified and stored by UK banks for seamless identity verification using existing online banking credentials. No app downloads, no friction.

Verify 50 million UK citizens’ IDs instantly

Using data already verified by institutions operating under some of the most rigorous KYC and data protection regulations, OneID allows you to instantly verify the identities of over 50 million UK citizens, without requesting any further information!

Using either document-free bank-verified data, eliminating the need for document uploads, or ID Scan where document-based identification is required, you get peace of mind and your customers rest assured knowing their data remains secure.

Whichever method you choose, you’ll reduce fraud risks, accelerate transactions, and create a seamless, compliant customer experience, whether during login, onboarding or signing.

With OneID now available in both Scrive eSign and Scrive eID Hub, businesses can offer UK users a trusted, compliant, and frictionless way to verify their identity, whether for signing agreements or authenticating online.

With OneID, you get:

High accessibility – OneID taps into online banking data for fast, reliable verification covering approximately 93% of UK adults.
No extra apps or downloads – Customers verify their identity using their existing mobile banking app or browser.
Rapid verification – Confirm identity or age in under 12 seconds, reducing friction in customer journeys.
Enhanced fraud prevention – Reduce fraud risks with secure, document-free verification.
Meet compliance requirements – Certified under the UK Government’s Digital Identity and Attributes Trust Framework (DIATF).

A proven concept in the Nordics, now in the UK.

Bank-based digital identity is already proven across the Nordics, where solutions like BankID and MitID enable millions of secure transactions every day.

Initially, these eIDs were primarily used for online banking and taxes but that’s not the case anymore. Now Nordic citizens use eIDs to access their local gym, buy tickets for public transport, verify their age and so much more, averaging at 3-4 uses per day per person!

Now, with OneID, UK businesses can benefit from the same trusted model, combining regulatory strength, convenience, and user familiarity in one streamlined experience.

Where to use OneID

OneID is ideal for banks, fintechs, and payment providers, credit and lending companies, subscription-based services requiring identity verification and more. Two of the reasons for that are:

Trusted signing experiences
Enhance security of digital agreements by leveraging bank-verified identities with signatures. Suitable for employment agreements, loan applications or real estate transactions, OneID ensure that every signature is verified and tied to an individual, reducing risk of fraud.

Faster, more secure logins
Reduce friction with instant, bank-based identity verification. Users log in seamlessly using their online banking credentials, improving both security and user experience.

Seamless onboarding
Speed up customer sign-ups and meet compliance requirements without manual document uploads. OneID verifies user identities in seconds, reducing drop-offs and administrative costs.
