2FA Authenticator Reviews and details

Social recommendations and mentions

• Is it a good idea to use Bitwarden for OTP?

  2FAS is a very solid MFA; Bitwarden is designed to be a password manager, so I wouldn't suggest using it as a 2fa. Keep it separate imho. Source: 5 months ago

• Ask HN: How to plan the big move from Android to iOS?

  > Is there anything as good as Firefox with UBO? The DuckDuckGo iOS app blocks ADs and trackers. Also ADGuard Pro can block stuff at the network level. It only costs $10.00 for a one time purchase. > My main concerns are will 2FA break? Make sure to export your QR code TOTP seed images into a new iOS app. Most TOTP apps allow you to do this. I like the app 2FAS[0]. > Can I keep using Google for photos and docs or... - Source: Hacker News / 5 months ago

• Google Authenticator cloud sync/backup is not E2E encrypted

• No More Mr. Nice Guy: GitHub Demands Developers Use 2FA

  The article suggests that users install Google Authenticator for 2FA, but I would suggest looking elsewhere. The developers pushed a change sometime within the last year where the app takes several seconds to respond when you first open it as well as when the codes refresh I have recently switched to 2FAS (https://2fas.com/#) which has been much more responsive so far. I'm also interested in hearing if anyone has... - Source: Hacker News / about 1 year ago

• Looking for an authenticator app that won't screw me over if I lose my phone.

  2FAS is a good one, open source and has cloud sync. Aegis Authenticator is a big favourite in the security/privacy/open source world, has cloud back up as well via android backups iirc. Source: about 1 year ago

• Suggested Password Manager

  I advise you to combine any password manager you chose with a 2-Factor Authentication app, I use 2FAS, but many prefer Aegis Authenticator. Both are good, there are many others too - but most people I've heard complain about Google Authenticator, so o stay away from it lol. Source: about 1 year ago

• would anyone happen to know if this is safe. I tried to login with my new phone and cant use authenticator app plus i don't have the txt file for the codes.

  I use https://2fas.com/ you can back up your keys with them. Source: over 1 year ago

• Heads up for everyone changing from Authy to their preferred authenticator

  2FAS for me. Simple, good interface, no cloud. Keys can be exported so you can use with multiple devices. Can auto backup to hidden folder in Google drive in case you plan a catastrophe scenario. Source: over 1 year ago

• 2FAS' Cloud Backups are Encrypted?

  Sorry, I couldn't find any info on this. Does anybody know if 2FAS' Cloud Backups are encrypted? And exactly where does the backup gets stored in iCloud? Source: over 1 year ago

• Need a new MFA Authenticator App on iOS - 2FAS vs. Raivo

  I'm trying to find a comparison between 2FAS and Raivo, both of which I've heard good things about, but I can't seem to find anything that makes one better than the other. I'm moving out of Authy right now, so I'd like to know what my options are for this. Does anyone have experience with either or both and can recommend one of them? Source: over 1 year ago

• Louder for bank executives at the back!

  Well, I guess we should use physical security keys like Yubico or an offline 2FA app like 2FAS for TOTP. SMS OTPs are the most vulnerable of these MFA methods, as someone from telco and bank employees can easily edit your CIF. Source: over 2 years ago

• yubikey everywhere or just for password manager?

  I would say it is totally fine to store OTP tokens on Bitwarden and very convenient as well. But if you use a secondary app for OTP tokens I recommend "2FAS" from google store https://2fas.com/ you can read the reviews in google store. Take a look, its very high ranked, higher than authy. Very clean, simple, manual back encrypted ups and google driven hidden and protected back up, only accessible by the app. Source: over 2 years ago
