2FAS features and specs

  • Enhanced Security
    2FA Authenticator adds an extra layer of security by requiring a second form of verification, making it harder for unauthorized users to access your accounts.
  • User-Friendly Interface
    The application features a straightforward and intuitive interface, making it easy for users to add and manage their accounts and authentication tokens.
  • Offline Access
    2FA Authenticator works offline, allowing users to generate authentication codes without an Internet connection, which is particularly useful in low-connectivity situations.
  • Cross-Platform Compatibility
    The app is available on multiple platforms, enabling users to sync their accounts and access their authentication codes from various devices.

Possible disadvantages of 2FAS

  • Device Dependency
    Losing access to the device with the 2FA Authenticator can lock users out of accounts, necessitating backup strategies like printing codes.
  • Potential for Misconfiguration
    If not set up correctly, there is a risk of misconfiguration that can lead to being locked out of accounts or decreased security.
  • Initial Setup Complexity
    For some users, the initial setup and configuration of two-factor authentication might be confusing or time-consuming.
  • Limited Recovery Options
    In cases where users lose their authentication device, recovery options might be limited, causing potential inconvenience or the need for support.

Why this product is good

  • Provides cleaner abstractions over goroutines, WaitGroups, and channels
  • Includes built-in panic recovery so goroutine panics don't crash your program silently
  • Offers convenient utilities like conc.WaitGroup, pool, stream, and iter for common concurrency patterns
  • Reduces boilerplate and the risk of leaked goroutines or forgotten synchronization
  • Backed by Sourcegraph and actively used in production code
  • Well-documented with a clear, idiomatic API

Recommended for

  • Go developers who frequently work with concurrent code

The Best Authenticator Apps for 2023
This simple but fully functional app does everything you want in an authenticator. It lets you add online accounts either manually or with a QR code. Unlike Google Authenticator, it can create cloud backups of your registered accounts, either in iCloud for Apple devices or Google Drive for Androids, which is critical if you lose your phone or get a new one. The backup is...

  • Playing with more user-friendly methods for multi-factor authentication
    FWIW 2FAS starts to show you the next code near the end of the window, this is very handy https://2fas.com/. - Source: Hacker News / about 1 year ago
  • Bitwarden Authenticator
    I personally switched to using 2FAS[0]. My favorite feature is that it comes with a browser extension that can automatically fill in the OTP on web forms, after approving the request on the phone app. [0] https://2fas.com/. - Source: Hacker News / over 1 year ago
  • Ask HN: AWS registering MFA will be required in 29 days
    I'd go with number 2 unless you want to buy everyone a hardware token (option number 3). There are open source solutions (I've used https://2fas.com/ ) and very common solutions (Google Authenticator). You can even print out the QR code and put it in a secure location (safe, safe deposit box) as a break-glass in case everyone's phones cease functioning. - Source: Hacker News / almost 2 years ago
  • Flaw has Microsoft Authenticator overwriting MFA accounts, locking users out
    Try 2FAS - it works without an cloud account, can import from few other apps (sadly not from Microsoft one) and can export from and import to a file. Works on Android and iOS https://2fas.com/. - Source: Hacker News / almost 2 years ago
  • Ente Auth: open-source Authy alternative for 2FA
    My hunt for an open source Authy took me to 2FAS, which has been fine. Any opinions on this offering? 2FAS โ€” the Internetโ€™s favorite open-source two-factor authenticator https://2fas.com. - Source: Hacker News / about 2 years ago

  • Go's race detector has a mutex blind spot
    > Actually much closer than anything I saw in other mainstream languages eg Java or Go. https://github.com/sourcegraph/conc. - Source: Hacker News / about 1 year ago
  • Show HN: Rill โ€“ Composable concurrency toolkit for Go
    Looks good, similar to https://github.com/sourcegraph/conc which we've been using for a while. Will give this a look. - Source: Hacker News / over 1 year ago
  • Show HN: Rill โ€“ Composable concurrency toolkit for Go
    Sourcegraph Conc is broadly similar in providing pool helpers, but doesn't provide the same fine grained batching options: https://github.com/sourcegraph/conc. - Source: Hacker News / over 1 year ago
  • Go Concurrency vs. RxJS
    JS concurrency is crap. It should be shot and buried in a lead coffin. Debugging async code is pure hell. With Go, you have a normal debugger that can be used to step over the code. You can get normal stack traces for all threads if needed. There is a race detector that can catch most of unsynchronized object access. With JS? You're on your fucking own. You can't find out the overall state of the system ("the list... - Source: Hacker News / almost 2 years ago
  • Three Ways to Think About Go Channels
    Not speaking on whether the language should make this easier without an external library, but wouldn't https://github.com/sourcegraph/conc help in that scenario? It has context-aware and error-aware goroutine pools, seems like the exact fit for what you are trying to do. Although admittedly I dive too deep into your code. - Source: Hacker News / about 2 years ago
