My main concerns were ease of use and functionality. Both are clear passes for me. I don't need an all-in-one solution or whatever. Just an app that allows you to use 2fa security. This app doesn't try to sell me anything, has a clean interface, and was very easy to use. The scanning of QR to add an app/website worked A-OK for me.

App works as intended (for the most part. I'll get to that). It works well on my phone. I also have the app on my tablet. Issue is, is when I have the tablet in vertical, everything works fine. When in horizontal however, the app freaks out and goes back-and-forth on having the codes in the center of the screen and on the left. Making horizontal useless.

The app stopped working on my phone leaving me locked out of my work accounts which I need the codes to get into. Edit: nothing weird happened before it stopped working. The app won't open past a blank white screen followed by an error message that says the app "keeps stopping". I updated, reinstalled, cleared cache and everything and it still didn't work. Edit 2: no, I don't want to have to download and sign up with another app just to get this solved.

John Behling

It's easy to set up, intuitive, and has always worked when I needed it. Also, not swimming in ads, which is a huge plus. I also just replaced my phone, and was worried about getting this set up on my new device. Turns out the tokens were backed up on Google Drive, so as soon as I installed this, BAM! Everything was there, already working. I couldn't be happier!

Moving from Authy to 2FAS. There's an issue where adding a 2FA entry incorrectly identifies the service being added. For example, both times I added a service where I'm using a Protonmail email address, 2FAS incorrectly autofilled the entry as being for OnMail. Edit: awesome, thank you. Not sure what kind of blockers prevent it, but I naming and icon selection should be handled automatically especially when the services exist in the database already.

Scott Marshall

Easy to set up, and the browser extension for using the auth codes in a desktop browser is very useful. One minor gripe: if a given service (eg Microsoft Online) has multiple accounts, the browser extension always and only uses the token from the first account listed for that service. This means that you can't use the browser extension when logging in to a service with anything other than the first account.

Anthony Pietrandrea

Love this app. It's clean, customizable, and the browser extension that allows you to enable push authentication for any service is genius. My only suggestion would be to add an option to hide categories if they're empty. I have all of my services categorized, yet the default group still appears at the top and displays 0 tokens. Please let me hide this and the app will be perfect.

So far, so good. A simple UI, a good sync option, optional dark mode, active search, and hidden tokens. I've tried the backup/sync between my phone and tablet for 1 account and will gradually be migrating everything from Authy, as I've had enough of them killing a good thing. For a 5* rating, I'd love to see tiles as an option as well as the current lists, landscape view to match when my tablet is in landscape mode, and a timer when tokens are hidden.
