📊 Best CIAM Solutions 2026: Passwordless & AI Compared
📱 Native App Passkey Errors: Ultimate Overview (2026)
We compared 12 CIAM platforms at 500k monthly active users, from Auth0 and Ping Identity down to Firebase and Supabase and the monthly bill swings from roughly 599 dollars to 30,000. But the number that should worry you is a different one: passkey adoption stalls at 5 to 10 percent on almost every platform, no matter how modern the login screen looks.
The post calls this the orchestration gap, the space between an API that technically supports passkeys and a flow that actually gets people to use them. A settings-only setup converts under 1 percent of logins to passkeys while a device-aware flow with identifier-first recovery clears 60 percent.
There is also a new column most buyers miss: whether the platform can hand an identity to an AI agent over the Model Context Protocol. And the real cost is not the license, it is the 25 to 30 FTE-months a custom passkey build burns before you even reach maintenance. So if your shortlist only weighs price and feature checkboxes, what is it quietly missing?
On the web a failed passkey is one generic DOMException. In a native app you finally see the real platform error codes, iOS ASAuthorizationError values and Android’s 50xxx Google Play Services messages, but you also inherit a far messier problem.
Eight things vary at once, OS version, app version, device brand, model, authenticator state and more, and Android’s median abort rate runs 10 to 14 percent against just 2 to 3 percent on iOS. The gap is fragmentation: flagship phones fail 3 to 15 percent of the time while budget devices can fail 75 to 90 percent, which is why a single universal alert threshold is useless. A 5 percent abort rate means something is broken on iOS but is a perfectly normal success rate on a cheap Android.
The tells to watch for are authentication loops, three or more failures within minutes on the same device, and silent device avoidance, users who quietly switch to the browser after the app fails them. Would your logs tell those two stories apart?
The CIAM you buy and the Android build you cannot control fail for the same reason: nobody is watching the passkey flow while it happens. Corbado Observe shows every enrollment and login as it runs, which users succeed, which ones abort and exactly which device and error code killed the attempt.
