Image from store GAuth Authenticator

Description from store A simple application which generates TOTP tokens when multi-factor authentication is used with your Google account. It implements RFC4226 (HMAC-based OTP) and has been tested to work with Google Authenticator, Dropbox, Dreamhost and Amazon. Not just to secure your GMail account, but also extremely helpful to tighten the security of your SSH connection as instructed at http://www.mnxsolutions.com/security/two-factor-ssh-with-google-authenticator.html Instructions: Enter the secret you have been given by the service for which you want to have the OTP generated. Acccount name is whatever you want to remind your secret by, eg. the site name or email address. The generated 6 character key is the response you will need to enter when asked for. Be aware the time on your desktop or phone should be synchronized. When this is off by a minute it could fail to login. If you are using Google, do not use an application-specific passwords to generate a response. They are not meant to be used this way. Please let me know about any problems before you make a review in the store since I cannot answer you there. Send a report email or report the support page. You can find the contact info in the about dialog or navigate to the support page. No data is transmitted. All token secrets are stored locally in localStorage. Online version available at http://gauth.apps.gbraad.nl Community created application. Not affiliated with Google. Source code is available at http://github.com/gbraad/gauth/ Have you got some idea?

(2023-08-30) Richard Davies: No documentation. No syncing, so can't import my existing 2FAs. Appears to only be useful if setting up a new 2FA - given I've already put all my 'at risk' accounts onto 2FA, makes this useless.
(2022-11-21) Peter Walsh: As soon as I installed this extension my inbox began being flooded with spam, it would seem the author is selling your email address and potentially other data.
(2021-08-06) Gregg Duncan: It works for a while but the timer gets out of sync over a very short time and you have to enter the code at the beginning of the 30 second count down for it to work.
(2021-04-29) John Weiss: no import
(2021-02-26) William Williamson: I love this app easy to use. When I consider how important 2Fa is to my information security, I have backed up my recovery codes in three different email accounts along with storing it at a safe place at my home. it is possible to recover your Authenticator.
(2021-02-15) Gergely Németh: Doe not work
(2020-11-10) Samuele Rivardi (MortiCat): Inaffidabile Il servizio si basa su una pagina web che "dovrebbe" registrare e riconoscere le key, ma dopo aver fatto la procedura di attivazione, chiuso il browser e riaperto, l'account è sparito e viene presentato un default "[email protected]" - per fortuna era un account di prova altrimenti ora sarei bloccato fuori. Totalmente inaffidabile
(2020-11-08) aaa bbb: Does what it suppose to do. Great app, thanks!
(2020-09-04) Raj: Idk why there are so many negative or comments like it's not working,etc. can't say those are bot comments either but it worked perfectly for me on my 1st try you can give it a try bcos it's just a 250 KB extension and most probably it'll work for you as well :)
(2020-08-23) Дракоша Пестренький (Drakosha): Расширение работает почти со всеми сайтами и в целом удобное. Однако имеет существенные недостатки: Ключи хранятся в открытом виде. Можете почитать самое главное тут: https://stackoverflow.com/questions/20130126/security-concerns-for-using-localstorage-or-chrome-storage-inside-chrome-extensi Ключи при этом хранятся в не синхронизируемой части chrome.storage. Вы не увидите их на другом компьютере, а после очистки личных данных или еще чего они будут потеряны. Соответственно на сайт уже вы не попадете. (Делайте их копию.) Странно почему к каждому токену нельзя добавить резервные коды которые сайты предлагают при создании ключа токена. И почему нельзя было зашифровать хранимые токены и спокойно синхронизовать их между компьютерами.
(2020-03-30) tony rada: ongoing process
(2019-10-17) Cole Herman: Randomly stopped working completely page will not load
(2019-08-26) William Rubin: Works correctly. Uses standard "TOTP" algorithm used by Google Authenticator to generate codes, which only requires a secret + the current time. The secret appears to be kept locally in the browser (localstorage). I don't see any confidential data getting sent back to the server (https://gauth.apps.gbraad.nl), which is good. User interface is a bit simplistic, but functional.
(2019-08-21) Robert Rosenwald: I've found this extension very useful for when my phone is in the other room. I still keep the Google Authenticator on my phone, and have had keys lost, but overall it's a real timesaver.
(2019-07-24) Santhosh Ram: Works very well for me

(2019-07-04) JT: ** Please read this entire review if you've had issues getting GAuth to work in place of Google Authenticator ** This extension seems to work as desired; a Google Authenticator (GA) substitute packaged as a Chrome extension. Although the setup instructions are simplistic, it didn't clearly describe how it can generate the same (read: IDENTICAL) authentication 6-digit codes that GA generates. This extension CAN do that, however you have to know how to properly set it up. My personal opinion is that this is the reason why many users have rated this extension so low, or complained about the lack of actual GA synchronization. This extension seems to use the same algorithm that GA utilizes, which enables it to produce the same codes. It DOES NOT connect to Google or sync with their service. This is an in-device numeric generator that only uses a synchronized time code via the internet to generate the codes. It is dependent on the pass key entered combined with the generated time code. As the developer states, no account information is submitted to Google or anyone else. Proper setup is crucial. Setup for GAuth as a Google Authenticator substitute is as follows: 1. Download and start the GAuth Chrome extension. 2. Go to the "Edit" pencil button and add a new "one-time password". 3. Create an entry name - something to signify what this code is for. Using your account name is not necessary. ** The next steps would be the same for how you'd setup for the GA 2-Factor Authentication ** 4. Go to the website or location that you want/need the 2 factor authentication for. If you've already used Google's GA 2FA and this website is already registered under your account, make sure to login. 5. Go to the site's settings or 2FA administration page. You're basically going to re-register (or re-setup) your Google Authenticator. 6. The 2FA setup will produce a QR code or barcode, AND will provide an alphanumeric longform key. This code is intended to either be scanned by your smartphone/tablet or transcribed into the Google Authenticator App. Take note of the longform code, and type it into the "Secret Key" field in the GAuth Chrome extension. 7. IMPORTANT - Perform the same steps on your smartphone/tablet; either scan the QR/barcode or manually type in the longform key. This will re-sync/refresh your Google Authenticator. 8. Verify that the 6-digit codes between GA and the GAuth Chrome extension match. This has worked for me, and I hope this helps clarify the setup & use of this extension for other users!
(2019-04-26) Dan: This doesn't actually store the keys on your local system but rather redirects you to a web page which stores them for you! This is completely unacceptable from a security standpoint let alone rather deceitful at its best and outright criminal at its worst. No idea how these keys are stored on this persons server or what they are doing with them!
(2019-04-12) Tanmay Gupta: Not at all authenticating and working.
(2019-04-03) Pavel Lumpov (Krivluxas): Вначале было норм, но потом google authenticator отвалился( где теперь коды получать?
(2019-04-02) FASIULLAH KHAN: best working nice app thanks for making this app
(2019-01-29) samad mousavi: How can I open another key?I have key but no accept in new phone
(2019-01-24) muy buena
(2019-01-11) Nevan Artwin Pratama Hidayat: It's Work. Only Three Step. Click Edit Then Click Add Next Complete The Requirements And Done!!!
(2018-12-21) Cary Jamison: Just barely started playing with it. Seems like a good start, but lacks some obvious usability features, like quickly being able to copy a code, maybe from a dropdown list on the extension icon.
(2018-08-01) Terry Canaan: Does nothing
(2018-07-25) Frank Sparacino: Lost all my keys.
(2018-07-18) Jacob Chen: Tested one key and it worked!
(2018-06-08) Gonzalo Diaz: Sin problemas
(2018-03-30) Eric Young: Flat-out does not work.
(2018-03-17) Raul Popa: doesn't work well, not using it.
(2018-03-06) Paolo Barone: Più che buono
(2018-03-02) Leny Fest: lo probare
(2018-02-21) Pavan Kumar Kora: Lost all the store keys after cookies and cache clean up
(2018-02-04) luca avitto: non va bene perchè non c'è la possibilità di sincronizzare gli account da verificare
