How do you handle KYC verification flow without breaking the user experience?

I’m building a fintech app for a client that needs to verify users during onboarding. We’re using a third-party KYC provider, but the verification flow feels clunky.

Users get redirected, the session sometimes times out, and a few drop off mid-way. I’m thinking of embedding it directly or reworking the UX flow, but I would love to know how others have balanced compliance vs smooth onboarding.

Any examples or anything?
