Tested on 2 machines with latest Firefox browser: Fetches for data forever, but nothing happens, no connection to the mobile app.

I really like all of the features of this app, especially the single-click request for TOTP code in browser extension generating a Push event to my phone with an Accept/Decline notification pop-up so you don't even have to open the app to send the code back to the OS clipboard and the browser extension.

Continues to improve great value.

unresponsive, the ` set up` button does nothin, currently unusable

The browser extension for this Authenticator app allows you to push the current OTP code directly to your browser instead of having to cram the number into short term memory and manually type it in. For the app itself, a solid set of features lifts this two-factor authentication (2FA) app head and shoulders above its competitors. With the ability to back up its data to the cloud, TOTP Authenticator protects you from a lost phone or device, unlike some other similar products from larger, more well-known competitors. The optional ability to require a PIN or fingerprint to access the app protects your security in the case that your device falls into the wrong hands. All around a well done app with robust free-tier features and a paid tier that adds true value as well. Get this app and add this extension to your browser clients!
