Browser started popping up unprovoked "promo-newtab.club" links which tried to redirect to Russian sites.

This plugin per grep below was the culprit found via the GUID in about:debugging#/runtime/this-firefox

$ grep -r 'promo-newtab' .

It is genuinely good. It works with my android phone and it syncs very well. No complaints

Alles zu 2FAS migriert.
Kann Export - Automatisches ausfüllen via Addon - fast perfekt! Fehlt nur ein Kurzbefehl zum triggern des 2FAS Addons im Browser.

Pointless because I have to look at my phone anyway to approve the request.

Extension isn't working, it says "Browser Extension data error, Please reinstall browser extension or contact with 2FAS Support on Discord" I've reinstalled the extension but the error is still there.

The extension should work standalone without smartphone.

Basically pointless. I tried this in the hopes of not having to hunt down and unlock my phone when needing a code, but you still have to do so. Why install another extension which requires full access to my browser for such an insignificant workflow change that isn't even easier.

You still need to manually approve on the mobile app each time you need 2FA.

I wanted 2FA authentication from my desktop, so I don't always need to grab my phone, log in, go to home screen, open the app, approve, BLAH BLAH. Still the same huge hassle with this extension.

For those people saying "bUT yoU wIlL gET HAcKeD!!!11!!", no, if this was an actual 2FA-extension then you would be able to set up your PC/Browser to be the second authentication.

Great app lock

After Authy announcing the end of their desktop app I was looking for an alternative and found 2FAS, an open source project (foss), it was my final choice because it has the option to export your data and therefore allowing you to migrate somewhere else easily if needed, thing that Authy didn't have... now if I want to change I'll just export it somewhere else, no more setting up all accounts again.

Funktioniert sehr gut. Empfehle zuerst das Video anzuschauen, dann seht Ihr wie es funktioniert. Und natürlich braucht man weiterhin sein Gerät mit der App (sonst wäre es ja auch mein MFA)

Fantastic

Requires a mobile application

Great extension, it trigger the mobile app to allow the OTP to be copied in the field on the website instead of having to write it yourself.

To all people complains that the extension triggers the mobile app to copy the code. YES, it's how you don't get hacked by easily let anyone access your OTP on your computer *facepalm*
If it bother you, you missed the purpose of 2FA/MFA. Continue writing your passwor on a post-it and put it on your screen edge.
