One of the biggest challenges for identity verification in the financial services is verifying users without creating unnecessary privacy risk, onboarding friction, and avoidable drop-off. Poor user journeys are costly, with Signicat showing that 68% of consumers had abandoned a financial services onboarding application at least once as their expectations of a “good” experience evolves, while the FCA’s 2025 Monzo enforcement action showed how weak onboarding controls can turn into a direct regulatory problem.
Digital onboarding and low-friction identity verification
Too many digital onboarding journeys still assume that stronger checks must mean more data collection. In practice, that often means asking users to upload documents, take selfies, or submit information the firm does not actually need.
Privacy-by-design takes the opposite view. Start with the minimum data required for the decision in front of you, then use a trusted verification method that gives you strong assurance without over-collecting. For customer onboarding, that can mean verifying core identity attributes through authoritative sources instead of defaulting to document upload.
At OneID® , we don’t require users to download any apps or scan documents by default. Instead, we verify age through digital IDs, bank-backed identity and telecom-verified data with explicit user consent.
Customer onboarding, onboarding fraud prevention, and account ownership verification
The challenge for fintech identity verification is that conversion and fraud prevention are often treated as opposing goals. They should not be. UK Finance reported £39.4 million in account takeover losses across 84,937 cases in 2024, which is a reminder that weak controls carry their own commercial cost.
Good financial services identity verification should therefore do two things at once: confirm the person is real, and confirm the account or attribute being used genuinely belongs to them. That is where bank-based identity and account ownership verification can be useful, especially for identity for account opening, fraud signals, and anti-fraud identity verification.
At OneID®, we reflect this approach by combining identity proofing, account-related verification, and reusable sign-in tied to a verified identity rather than just a password or email address.
Conversion-focused identity verification for account opening
The firms that will be successful with digital onboarding are unlikely to be the ones collecting the most data. They will be the ones proving enough, at the right moment, with the least friction and the clearest audit trail.
If you are reviewing your customer onboarding or onboarding verification journey, OneID® leads the way for teams that want stronger assurance, lower friction, and less reliance on document uploads and selfies.
