Before you can create or use passkeys on your iPhone with Kuda, enable iCloud Keychain and passkey AutoFill. Passkeys are surfaced through Apple's AutoFill flow with Face ID, Touch ID, or your device passcode.
Why iCloud Keychain is required
iCloud Keychain:
Securely stores your passkeys.
Syncs passkeys across Apple devices using the same Apple ID.
Is required by iOS for passkey storage and sign-in.
Passkey AutoFill is configured separately from other AutoFill options.
Steps to enable iCloud Keychain
Open Settings.
Tap your Apple ID (your name) at the top.
Tap iCloud.
Tap Passwords and Keychain.
Turn on Sync this iPhone.
Authenticate with your Apple ID password, Face ID, or Touch ID if prompted.
Enable AutoFill for passkeys
Open Settings > Passwords > Password Options.
Turn on AutoFill Passwords and Passkeys.
Select iCloud Passwords & Keychain as the source.
Ensure Face ID & Passcode (or Touch ID) and a device passcode are enabled.
Verifying it works
Settings > [Apple ID] > iCloud — confirm Keychain shows On.
Wait a few minutes for the initial sync.
Settings > Passwords — confirm a Kuda passkey appears after setup.
Sign in to Kuda with Face ID or Touch ID when prompted.
If AutoFill is not working for passkeys
Confirm iCloud Keychain is selected under AutoFill sources (Password Options).
Confirm Face ID, Touch ID, or your device passcode works.
Check your phone’s connectivity and make sure iOS is up to date.
Restart your iPhone if the settings will not stay enabled.
Some setups require scanning a QR code for cross-device sign-in—follow the on-screen prompts.
Additional information
iCloud Keychain is encrypted; enabling it does not remove existing passwords.
Passkeys work with compatible apps such as Kuda.
Reconfiguration is only needed if you sign out of your Apple ID or switch Apple accounts. Switching accounts breaks access to passkeys stored under the previous Apple ID.
