Authenticator Pro is your all-in-one account security app — two-factor authentication (2FA), a password vault, a password generator, and a private secure browser, all in one place. Whether you're protecting your personal logins, running stores on Amazon and Shopify, or managing dozens of developer and company accounts, Authenticator Pro makes account security simple, reliable, and effortless. CORE FEATURES • Two-Factor Authentication (2FA) — your first line of defense Built on the TOTP standard, Authenticator Pro works with every major service: Google, GitHub, Amazon, Shopify, Microsoft, Dropbox, X (Twitter), Discord, PayPal, Stripe, and any platform that supports two-factor or multi-factor authentication (MFA). Just scan the QR code and you're set up in under 30 seconds. Your one-time codes (OTP) refresh every 30 seconds, so even if your password leaks, no one can sign in without the code. • Password Vault — stop using one password everywhere 80 accounts, 80 different passwords — impossible to remember, and you don't have to. Every username and password is encrypted and stored locally on your device, ready to copy with a single tap. No more digging through notes, sticky notes, or chat history — and no more endless "forgot password" resets. • Password Generator — strong passwords in seconds Create high-strength passwords with custom length (5–64 characters) and any mix of uppercase, lowercase, numbers, and symbols. The result would take trillions of years to brute-force. Signing up for something new, or forced to rotate a password? Generate, copy, done — in five seconds. • Built-in Secure Browser — your last line against phishing Phishing is one of the most common ways accounts get stolen, and fake login pages are nearly impossible to spot. The built-in secure browser runs in an isolated sandbox that blocks third-party ad tracking and cookie monitoring. Switch on private mode and all history and local data are wiped the moment you leave — no trace left behind. Smart autofill even recognizes login pages and fills in your saved credentials with one tap. • iCloud Sync & Cloud Restore — switch phones with zero stress Losing every code when you get a new phone is a nightmare too many people know. With iCloud sync on, your accounts are automatically encrypted and backed up to your private iCloud. Install the app on your new phone and restore everything in 30 seconds. • Apple Watch — codes on your wrist Phone not handy? Just raise your wrist and read your verification codes right on your Apple Watch. • Face ID / Passcode Lock With app lock enabled, Authenticator Pro asks for Face ID or your passcode every time it opens — so even if someone gets hold of your phone, your accounts stay safe. WHO IT'S FOR • Everyday users — protect your email, social, banking, and shopping accounts • E-commerce sellers — keep your Amazon, Shopify, and eBay store accounts safe, especially before peak season • Developers — manage GitHub, AWS, GitLab, and cloud accounts in one place • Crypto traders — secure your Binance, exchange, and wallet logins • Gamers — protect Steam, Riot, Epic, and other game accounts • Teams — centralize accounts and hand them off seamlessly with iCloud sync Account security isn't something to handle "after something goes wrong." Download Authenticator Pro today, set up in five minutes, and put every account in the vault.

Verdict
The clearest difference is rating: DOO at 5.0 against Authenticator's 4.5. Authenticator's advantage is update cadence (weekly vs every 2 weeks) and device support (4 vs 1). On price, ratings volume, ads and in-app purchases there is nothing between them.
