Contacts Backup & Sync vs Authenticator

Contacts Backup & Sync makes it effortless to protect and manage your address book. Create reliable backups, export in the formats you need, and keep contacts synchronized across devices and cloud accounts—without generating duplicates. Save backups to your device or share them via email and the iOS Share Sheet to your preferred apps and storage services. Export in many formats for smooth transfers and easy restorations. Connect your Google and Microsoft accounts (Outlook, Live, Hotmail, and more) to sync one-way from device to cloud, cloud to device, or two-way. The app automatically detects duplicate entries, guides you through clean merges, and prevents new duplicates during sync. Quickly find incomplete entries—missing name, phone number, or email—so you can clean and organize in minutes. View contacts by company or groups, and see upcoming birthdays at a glance, including grouping by birthday. The app is free to use. Upgrade to Contacts Backup & Sync Pro via in-app purchase to unlock all features with no limits. We respect your privacy—your contacts remain under your control and are never shared without your consent.

Authenticator keeps everything a login needs in one private place: your 2FA codes and your passwords, organized into Codes and Passwords tabs, with backup codes on the same card as the account they belong to. Most of us juggle a separate authenticator app, passwords scattered across notes, and recovery codes buried in screenshots. Authenticator brings them together. Add an account once and its verification code, password, and backup codes live together. Add a credential for a service you already have and Authenticator offers to merge it, so everything about one login stays in one place. PRIVATE BY DESIGN - Optional app lock: protect the vault with Face ID and/or a 6-digit passcode — your choice. - Nothing leaves your iPhone. No account to create, no company server. Your secrets live in your device's Keychain and, if you turn it on, your own iCloud Keychain. - Copied codes clear from the clipboard automatically. BUILT FOR EVERYDAY LOGINS - Live 2FA codes with a ring that drains over each 30-second window. - Add by scanning a QR code or by entering details yourself. - Passwords with tap-to-reveal and one-tap copy. - Backup codes you can mark as used, so you always know which are left. - Search and pin the accounts you reach for most. FAIR BY DEFAULT Viewing, revealing, and copying what you have is always free — your data is never held hostage. Authenticator Pro is an optional subscription that adds unlimited accounts, iCloud Keychain sync across your devices, and encrypted export (file or paper backup). Weekly, monthly, and yearly plans are available. Authenticator stores, shows, reveals, and copies your logins on iPhone. It does not autofill into other apps.
