A passkey is a cryptographic credential stored on your device or in a password manager. Instead of typing a password, you authenticate using Face ID, Touch ID, a PIN, or a password manager that supports passkeys. The device or manager handles the verification — nothing secret is typed or transmitted.
Passkeys are phishing-resistant and sync across your devices through iCloud Keychain, Google Password Manager, or any FIDO2-compatible password manager. Hardware security keys (such as YubiKey) also work as passkeys but are bound to the physical device and do not sync.
Note: Passkeys are currently in preview. The feature works but shows as Coming soon in the dashboard while the rollout is in progress.
How they work
You enrol a passkey during sign-in. After signing in with your password, Sinch ID asks if you want to save a passkey to your device. Once enrolled, you can use it to sign in instead of your password.
Where passkeys are stored
Passkeys are stored and synced by your device's platform or password manager:
- Apple devices: iCloud Keychain syncs your passkeys automatically across all your Apple devices signed into the same Apple ID.
- Android devices: Google Password Manager syncs passkeys across Android devices signed into the same Google account.
- Cross-platform password managers: 1Password, Bitwarden, and other FIDO2-compatible managers sync passkeys across all platforms (iOS, Android, Windows, macOS).
- Hardware security keys(YubiKey and similar): stored on the physical device and not synced anywhere.
Signing in from a different device
If your passkey is stored in iCloud Keychain or Google Password Manager, it is available on all your synced devices automatically, with no extra steps needed.
If you are on a device that does not have your passkey, the sign-in screen will not offer passkey authentication. Use Continue with password instead to sign in with your password. After signing in with your password on a new device, Sinch ID will prompt you to enrol a passkey on that device too.
Lost passkey access
If you lose access to your passkey because your device was lost, wiped, or the passkey was deleted from your password manager, you can still sign in using your password:
- On the sign-in screen, enter your email address and select Continue with password.
- If you have MFA enroled, you will be asked to complete a verification step.
- Once signed in, go to Sign-in & Security and remove the orphaned passkey entry under Passkey.
- Sinch ID will prompt you to enrol a new passkey on your current device.
