Overview

The PassAgent iOS app is a native SwiftUI application for iOS 17+ that provides full vault management and system-wide credential autofill.

​
Features

  • Vault management: view, add, edit, and delete credentials
  • AutoFill extension: system-wide autofill in Safari and all apps
  • Passkey provider: provide passkeys through the iOS credential provider API
  • Biometric unlock: Face ID and Touch ID for quick vault access
  • Offline access: cached vault data for offline credential lookup

​
AutoFill extension

The AutoFill extension uses the ASCredentialProviderViewController API to provide credentials system-wide:
1

Enable AutoFill

Go to iOS Settings > Passwords > AutoFill Passwords and enable PassAgent.
2

Authenticate

When a login form appears, tap the PassAgent suggestion. Authenticate with Face ID or Touch ID.
3

Fill credentials

The matching credential is filled into the login form. If multiple matches exist, you can browse and select.

​
Passkey support

The iOS app provides passkeys through the same credential provider extension:
  • Passkeys registered through PassAgent are available in Safari and all apps
  • Authentication uses device biometrics (Face ID / Touch ID)
  • Travel-safe passkeys remain accessible in restricted environments

​
Requirements

  • iOS 17.0 or later
  • iPhone or iPad
  • Face ID or Touch ID (recommended for biometric unlock)
