The app generates time-based one-time passwords (TOTPs) that are used in conjunction with a user's login credentials to access online accounts, services, and applications. With its simple set up process, support for a wide range of services and applications, and high level of security, Authenticator App is an ideal solution for anyone looking to enhance their security and protect their online identity. Features: -Easy to set up Authenticator App is incredibly easy to add a new account. Users simply need to scan a QR code provided by the service or enter a secret key, which generates a unique six-digit code that changes every 30 seconds. This code is then used as a TOTP to access the account. -Highly secure The app uses time-based one-time passwords (TOTPs) to generate unique, time-sensitive codes that cannot be guessed or reused. Additionally, the app is protected by a PIN code or biometric authentication, such as Touch ID or Face ID, ensuring that only authorized users can access the app and view their codes. With these security features, users can be confident that their accounts are protected from unauthorized access and hacking attempts. -Password storage protection Password storage protection is a secure and convenient way to store and manage your passwords for various online accounts. With advanced security measures, ease of use, and automatic syncing, it allows you to keep your sensitive information private and protected from unauthorized access. -Password generator A random password generator is a tool that creates unique, strong passwords for online accounts. It generates passwords using a combination of letters, numbers, and symbols, making them difficult for hackers to guess or crack. -Supports 1000+ Apps Authenticator App supports a wide range of services and applications, including Google, Facebook, Dropbox, Amazon, and more. -Backup and sync With Auto-Sync on, you can easily back up your 2FA accounts to your iCloud.

ReceptionRating · Positive reviews · Number of ratings

OPark holds the better App Store score, 5.0 against 4.3. That said, the two scores are not equally well evidenced: Authenticator App ` has 31 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 30% of Authenticator App `'s written reviews are positive against 5% of OPark's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Authenticator App ` ships an update every 2 months, OPark monthly. Both last shipped on October 13, 2026.
