iOS passkey readiness in Mar 2026, with the preceding three months of history available below.
As of Mar 2026, passkey adoption on iOS is measurable across Safari (WebAuthn 100%, passkey-ready 95%, synced passkeys 100%) and Chrome (WebAuthn 100%, passkey-ready 85%, synced passkeys 100%). Based on Corbado's passkey intelligence, these figures cover the last three months (Jan 2026–Mar 2026).
Safari is the default browser on iPhone and carries the majority of passkey traffic on the platform. Chrome on iOS runs on WebKit under the hood and reaches the same iOS system passkey sheet, which is why passkey-readiness is broadly comparable across both.
In Mar 2026, Safari on iOS had WebAuthn available to 100% of users and was passkey-ready (via Face ID / Touch ID via iCloud Keychain) for 95%, and 100% of created passkeys synced across the user's devices. Safari on iOS uses iCloud Keychain as the passkey store and Face ID or Touch ID to confirm sign-in.
| Month | WebAuthn | Passkey-ready | Synced passkeys |
|---|---|---|---|
| Jan 2026 | 100% | 97% | 100% |
| Feb 2026 | 100% | 96% | 100% |
| Mar 2026 | 100% | 95% | 100% |
In Mar 2026, Chrome on iOS had WebAuthn available to 100% of users and was passkey-ready (via Face ID / Touch ID via iCloud Keychain) for 85%, and 100% of created passkeys synced across the user's devices. Chrome on iOS delegates to the iOS system passkey sheet rather than bundling a separate authenticator, so the underlying security surface matches Safari.
| Month | WebAuthn | Passkey-ready | Synced passkeys |
|---|---|---|---|
| Jan 2026 | 100% | 66% | 100% |
| Feb 2026 | 100% | 38% | 100% |
| Mar 2026 | 100% | 85% | 100% |
Yes, effectively. Every browser on iOS uses WebKit and delegates passkey authentication to the iOS system sheet, which reads from iCloud Keychain. That means a passkey created in Safari is also usable in Chrome on iOS without a separate enrollment, and the passkey-ready percentage is similar across both browsers in practice.
iOS 16, released in September 2022, introduced passkey support using iCloud Keychain as the credential store and Face ID or Touch ID to confirm sign-in. Later iOS versions added conditional UI, improved sync via iCloud, and expanded cross-device sign-in so an iPhone can sign in to a site open on a Windows or Android device.
Yes, provided the other device is signed into the same iCloud account with Keychain enabled, or the user authorizes the other device through hybrid transport via QR code. Apple also supports passkey sharing through shared groups in iCloud Keychain so family members can access specific credentials without logging into each other's Apple IDs.
The same three-month window for the other major operating systems, with their latest passkey-ready and sync figures.
Each percentage represents the share of iOS visitors in that month for whom the feature was technically available, not the share who actually used a passkey. Numbers are drawn from many sites so they reflect what the average iPhone or iPad visitor sees today. Inputs combine Corbado's internal data with public demo and tooling surfaces such as the Passkeys Debugger. See the full operating system and browser matrix on the homepage.
