I recently led a migration from password-based authentication to passkeys for a mid-size SaaS product using Okta as our identity provider. The project forced us to balance security wins with real-world usability: passkeys dramatically reduce phishing and password reuse risk, but they also introduce new failure modes that can frustrate users if you don’t plan carefully. In this piece I’ll walk through a practical rollout plan, the UX traps I encountered, and robust fallback strategies you can implement so your users don’t get locked out.
Why move to passkeys with Okta?
Passkeys (platform-backed credentials using WebAuthn/FIDO2) are an evolution beyond passwords and even traditional 2FA. They provide phishing-resistant strong authentication, often more convenient for users (biometrics or device PIN), and reduce support costs related to password resets. Using Okta makes integration smoother because it supports WebAuthn and passkey-style flows through its Identity Engine and Authentication APIs.
That said, moving from passwords to passkeys isn’t a simple flip of a switch. You own the UX, support flows, device compatibility edge cases, and regulatory obligations. Here’s a pragmatic plan that worked for us.
Rollout plan: phased, measurable, and reversible
I recommend a phased approach with clear gates and metrics at each stage. Our plan had these phases:
Discovery & compatibility mappingPilot with internal users and power usersOpt-in public rollouts with incentivesGradual enforcement with robust recoveryDefault-on for new accounts and deprecation plan for passwordsKey checkpoints and metrics:
Passkey creation success rate (%)First-login success with passkey after creationSupport tickets per 1,000 users related to authRecovery flow usage and success rateStop the rollout if you see a significant spike in support requests or a low passkey creation success rate in a representative sample.
Implementation checklist with Okta
From my experience the technical work can be summarized:
Enable WebAuthn in Okta (Identity Engine or Classic: review docs for your org type).Decide whether to store passkeys in Okta (Credential Management) or delegate to relying parties—Okta can act as the authenticator facilitator for many flows.Add UI flows for passkey creation and authentication using the Okta Authentication API and WebAuthn client APIs (navigator.credentials).Implement attestation and relying-party validation per WebAuthn best practices; Okta handles parts of this for you.Instrument analytics and logging for success/failure codes from navigator.credentials and Okta responses.Test on target browsers and devices (Chrome, Edge, Safari, iOS, Android manufacturers).Small implementation note I wish we’d emphasized earlier: return clear, actionable error messages from the client to the user. The raw WebAuthn errors are opaque; translate them into plain language (“Try enabling biometrics on this device” rather than “NotAllowedError”).
UX traps and how to avoid them
Passkeys change assumptions. Here are the traps that tripped us and how I recommend avoiding them.
Hidden setup friction: Users expect an instant “Sign in with biometrics” flow. But before that, you must create a passkey. Don’t hide this step — guide users through creation with a short modal and progress indicators.Device non-portability confusion: If users create a device-bound passkey and later switch phones, they may be locked out. Mitigation: present clear messaging about linking a backup device, using cloud-synced passkeys (Apple/Google ecosystem), or adding alternative authenticators during setup.Browser and OS gaps: Safari on older macOS/iOS versions and some Android browsers behave differently. Maintain a compatibility checker on the login page and show fallback options if passkeys aren’t available.Ambiguous recovery options: Recovery is the biggest UX failure point. Users hit “I can’t sign in” and expect straightforward help. Provide step-by-step recovery with identity verification and clearly present options (backup codes, secondary authenticator, support escalation).Overly prescriptive enforcement: Forcing passkeys too early causes churn. Use opt-in and communicate benefits; make passkeys the default for new accounts while keeping a graceful path for legacy users.Fallback and account recovery strategies
Design a layered fallback model. In our rollout we used a combination of:
Secondary authenticators: Allow users to register a second passkey, a security key (YubiKey, Titan), or enable Okta Verify as a backup.Cloud-synced passkeys: Encourage users on Apple/Google platforms to use built-in cloud-synced passkeys. Provide instructions and explain trade-offs (convenience vs. vendor lock-in).Recovery codes: One-time codes generated upon passkey registration and safely stored by the user. Treat these like a last resort — they must be revocable and one-time-use.Identity verification flow: For high-value accounts, offer a guided recovery path involving KBA (if compliant), OTP to verified email/phone, support ticket with manual identity verification, or video ID checks for sensitive cases.Customer support playbook: Equip your support team with a clear runbook: verify identity, re-provision passkeys or register alternative authenticators, log the incident, and advise the user on best practices.Operational and security considerations
Passkeys shift where risk resides. Here are operational points I kept on a dashboard:
| Risk/Concern | Mitigation |
| Device compromise | Require device locks/biometrics; detect anomalous sign-ins and step-up auth |
| Account recovery abuse | Rate-limit recovery, enforce strong identity checks, log and alert on multiple recovery attempts |
| Vendor dependency | Support multiple authenticator types; document export/import options |
| Regulatory audit | Keep auditable logs of passkey creation and recovery flows; provide evidence of user consent |
Also instrument risk signals in Okta (unusual device, location, or IP) and consider adaptive authentication: require additional steps for risky logins even if a passkey is present.
Testing and metrics I used
We ran targeted tests across device types and user segments. Some test cases you should automate or validate manually:
Passkey creation and login on latest/old versions of Chrome, Safari, Edge, iOS Safari, Android Chrome.Passkey portability: create on phone, login on laptop with cloud-synced passkeys vs device-bound.Recovery flows including use of codes, secondary authenticator, and support-assisted recovery.Attack simulations: simulate phishing and MITM attempts (passkeys should block these).Metric thresholds that triggered rework for us:
Creation success rate below 95% in a representative sample.Support tickets per 1,000 users increase by more than 20% post-rollout.Final operational tips from the field
A few practical learnings I wish I’d documented earlier:
Communicate early and often. Explain benefits, expected steps, and recovery options in plain language via email, in-product banners, and help docs.Provide an in-product compatibility checker and a short “what to expect” modal before passkey creation.Instrument everything — from JS WebAuthn error codes to Okta API responses — so you can triage issues quickly.Train your support team with scripts and escalation paths. Real people will still need help early in the transition.Consider a hybrid period where passwords remain valid but are discouraged; show progressive nudges to register a passkey.Switching to passkeys with Okta is one of the most impactful security upgrades you can make, but it requires thoughtful UX and recovery design. Plan your phases, test broadly, and give users clear, actionable guidance — you’ll get both stronger security and happier users when you do it right.
