I'm not sure what all of the fuss is about. You really don't want to be able to access your tokens from the web browser. You're creating another "point of failure." The less avenues for someone to be able to access your 2fa tokens, the better. To the dude who said, "So if I don't have my phone at hand, I am SOL." -- why in the world would your phone not be near you? In any case, if it isn't for some weird reason, I also have the app on my Apple Watch. This is much easier than quickly trying to open my phone and hope I type the token fast enough before the timer runs out and have to type in the new one. Step 1: Login to website Step 2: Website asks for 2fa token Step 3: Use either shortcut (kb shortcut is faster. I set mine to CTRL-SHFT-X) or click the extension icon on the toolbar. Step 4: Open the PUSH notification on your phone and select the website, then it gets auto-filled out in your web browser and you're done. It goes by super fast, less than 10 seconds. It's open source so the code can be audited. It's on both iOS, watchOS, and Android (unsure about wearOS). You can export and import your tokens. You can back them up to cloud. This is all free and it works perfectly. If you want an extension that autofills your tokens, go support Bitwarden and give them $10 for the premium feature, they deserve it. Otherwise, deal with the 10 seconds it takes for this extension to do its wonderful job. The only con I can think of is having to make the extension recognize I need a token so we have to either click the extension icon or use the kb shortcut. I'm not even sure if it's possible for an extension to recognize a website is asking for a 2FA request or not, but if its, having that process automated would be a nice QoL update. Either way, it took me too long to remember this extension existed, I wish I had downloaded it 2 years ago.

Garbage. It brings up app in mobile phone then does nothing. What's the point?
