Top 6 Google Authenticator Alternatives in 2023
One complaint about Google Authenticator is that it’s no longer open-source, with the relevant repositories not updated for several years. This isn’t an issue with FreeOTP, however, as it’s completely open-source.
The Best 2FA Apps 2021: Locking Down Your Online Accounts
The only apps we wouldn’t recommend are paid ones. For example, Authenticator Plus on Google Play is rife with issues, and it costs $2.99. There are plenty of free options available, and if you don’t trust the likes of Google and Microsoft, there are open-source options like andOTP and FreeOTP.

  • Regarding Yubikey
    People refer to blue keys as 'old' but yubico.com is clear...Security Key Series has been updated to black in 2023 with the same features as the Security Key Series in blue. Blue keys only available through partner sites. Source: about 1 year ago
  • Can't log in on mobile – Yubikey 5C NFC
    Sorry if this has been asked a lot already - I've tried searching yubico.com and this subreddit, but I haven't found a fix for it. Source: about 1 year ago
  • Why passkeys from Apple, Google, Microsoft may soon replace your passwords
    And this is what passkeys fix. So instead you get your parents a set of yubi-keys for their access to 1-pass. * Whenever they are using a known machine (their laptop, phone, etc.) an biometric+device security is used, that's your 2FA. * When in rare machines, or doing things that are probably not ideal (like trying to load and read account information stored in the password manager) they'd have to pull up...

  • First Yubikey lasted almost 10 years, here’s hoping for another 10!
    You know how sites ask you to use 2FA by texting you a code and having you put it in? It lets you do that by pressing the gold button on the front. It's better than using phone multifactor authentication, because it's possible for hackers to either trick you into giving them 2FA codes (There's a video on the front page of yubico.com right now explaining how that can happen), or to manipulate your phone carrier...

  • Google Authenticator
    Not a solution to your exact problem, but since you're already in this pickle, I recommend getting a couple security keys (Yubikeys directly from yubico.com). You can then use Yubico's authentication app + security key which works with any service requiring an authetication app (including CDC - this is what I use). It's much easier to restore and a lot more secure. Source: over 1 year ago
