Proton Authenticator for iOS is the official two-factor authentication client for iPhone and iPad, providing secure generation and management of TOTP codes for users’ online accounts while prioritizing privacy and encrypted secrets storage. Written in Swift with native iOS APIs, it supports scanning QR codes to add new authentication tokens, auto-sorting entries, and fast entry selection, all within a sleek, responsive iOS interface. The application encrypts secrets on the device and uses Proton’s encrypted sync service if enabled so that users can recover or replicate their authentication tokens across devices without compromising security. ...

...The app generates time-based one-time passwords (TOTP) and counter-based one-time passwords (HOTP) that are widely required for logging into services with enhanced security, and it lets users scan QR codes or manually enter secret keys to register new accounts. Designed with native iOS conventions, it supports Face ID and Touch ID to quickly unlock the app while keeping authentication secrets encrypted locally on the device, so sensitive data never leaves the user’s control. The client is also structured to work offline, meaning you can generate codes without a network connection, and it integrates with companion browser extensions or other 2FAS sync tools so tokens can be backed up or restored across devices securely.

...It helps users replace or supplement traditional SMS or email 2FA by securely storing OTP secrets and displaying rotating codes that can be synced via iCloud across Apple devices, reducing the risk of losing access when switching devices. Users can easily add new accounts by scanning QR codes or entering secrets manually, assign custom icons for better visual organization, and quickly search through stored tokens to find the one they need. The app includes optional biometric unlocking with Face ID or Touch ID so access to sensitive OTPs remains both fast and secure. It also supports encrypted backups and exports, letting users archive their data safely offline or transfer it between devices.

Aegis Authenticator is a free and open-source two-factor authentication (2FA) app for Android that helps users secure their online accounts by generating cryptographic one-time passwords (OTPs) such as TOTP and HOTP codes. Unlike many proprietary MFA apps, Aegis is designed with user privacy and local control in mind, storing secrets only on the device in an encrypted vault protected by PIN or biometric unlock, and offering features like backups encrypted with a user-chosen passphrase. It supports importing accounts from QR codes, exporting encrypted backups for safe storage, and grouping or labeling tokens so managing dozens of accounts is simple. Aegis also offers options for custom token configuration, including changing issuer names, digits, and intervals, and includes a robust recovery mechanism in case a device is lost. ...

...It also supports backup and encrypted sync with the associated Proton account, helping users recover 2FA codes across devices — a feature that many standalone token generators lack without risking security trade-offs.

2FAS Auth for Android is the general Android authenticator client for the 2FAS open-source multi-factor authentication suite, designed to help users protect their online accounts with secure, rotating one-time passwords and optionally manage related vault entries. This client lets users add and view TOTP and HOTP tokens for countless services, restore and backup token sets across devices, and secure the app with passcodes or biometrics. The Android implementation emphasizes straightforward...

Open source two-factor authentication for Android. It implements Time-based One-time Passwords (TOTP) and HMAC-Based One-Time Passwords (HOTP). Simply scan the QR code and login with the generated 6-digit code. This project started out as a fork of the great OTP Authenticator app written by Bruno Bierbaumer, which has sadly been inactive since 2015. By now almost every aspect of the app has been changed/re-written so the fork status of the Github repository got detached upon user request. But all credit for the original version and for starting this project still goes to Bruno.
