About

Authenticator

Features
Read full description

Authenticator helps you manage authentication codes and organize your saved credentials on iPhone and iPad. KEY FEATURES • Authentication codes: Generate TOTP and HOTP codes for compatible online services. Add accounts by scanning a QR code or entering setup details. • Encrypted local vault: Store logins, passwords, payment details, Wi-Fi credentials and notes in an encrypted file on your device. • Optional iCloud backup: Back up and restore your vault through your private Apple CloudKit database. Cloud backups use Apple's CloudKit protections; local vault encryption does not mean app-managed end-to-end encryption of cloud backups. • Security checks: Check passwords against Pwned Passwords and manually check an email using LeakCheck. Checks require a network connection and reflect the providers' available records; no match is not a guarantee of safety. • Private browsing sessions: Browse using nonpersistent website storage. Websites still receive normal requests, and bookmarks you choose to save remain available. • Password generator: Create random passwords with your preferred length and character options. • AutoFill: Use supported saved credentials in Safari and compatible apps. • App lock: Protect access to the app with a PIN and supported biometric authentication. Some features require a subscription. Prices and available offers are shown in the app before purchase.
